Christ has entrusted the church with the responsibility to identify who is making a credible profession of faith in Christ, based upon their life and testimony, and who is therefore baptized into the visible body of believers known as the church. This is a major aspect of what church membership is all about. It’s about individual believers expressing a desire to be united to a true, biblically sound church, and in turn, that church mutually affirming professing believers as members of the body with all the privileges and responsibilities that come with that reciprocal relationship. 

What authority does the church have in the world? Not only is this an important question, but it’s a question that has been at the center of recent conversations concerning the topic of  Christian Nationalism. Yet, when we consider the purpose of the local church, we must understand that this is also a question that gets to the very heart of the church’s God-ordained foundation and function. Therefore, the more specific question we need to be asking is this: What authority has Christ given the church? 
As we prepare to answer that question, we need to begin in the Old Testament. There, we discover that, under the Old Covenant, three offices comprised the divinely designated representatives of God. Those representatives of heaven included the prophets, who declared, “Thus says the Lord,” as they spoke to the people of God on behalf of God (Isa 4:22). It included the priests, who mediated the Old Covenant through sacrifices (Lev 9:15). And it included the kings, who ruled and reigned over the children of Israel (2 Sam 2:4). But now, through the New Covenant, Jesus has been revealed to be the fulfillment of all three of those Old Testament offices. He was and is the ultimate Prophet, Priest, and King. As the Word of God made flesh, Jesus is the Prophet who always proclaims the truth of God (Deut 18:15; John 1:1). As the Mediator of a new and eternal covenant, he is the High Priest, who himself has become our once, for-all-time, sacrifice (Heb 4:14). And as the one who reigns from heaven and will reign on earth, he is the King of kings and Lord of lords (Rev 9:16).
Like a divine rope with three strands, it is by this three-fold office that the crucified, resurrected, and ascended Christ now leads his church to carry out the gospel mission, as his ambassadors and representatives upon the earth. As Paul writes in 2 Corinthians 5:17–21:
Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God. For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.
The Authority to Make Disciples
So, when was this ambassadorial authority given to Christ’s followers? To see that, we turn our attention to the gospel of Matthew. As we do, it’s worth noting that Matthew’s gospel is primarily focused on helping Jewish believers understand how Jesus, the Messiah and King, has inaugurated his Kingdom and how he expects his Kingdom citizens to live and operate. Of course, as Jesus enters the scene of redemptive history, as recorded in the gospels, he is doing so as the one who has all authority. And, with that authority, he makes a fundamental shift in who represents heaven on earth.
We find that exact moment in Chapter 28 of Matthew’s gospel. Even before his crucifixion, Jesus had commanded his disciples to meet him in Galilee after he was raised from the dead (Mark 14:28). Following that instruction, along with a helpful reminder from an angel at the tomb, the disciples meet the resurrected Christ on a mountain in Galilee (Mark 16:7). As he appears to them, Jesus begins by establishing his all-encompassing authority, declaring, “All authority in heaven and on earth has been given to me” (v. 18). Notice, that no domain is excluded in this proclamation. Jesus is saying, unequivocally, that everyone and everything, both in heaven and on earth, is within the realm of his sovereign rule and reign. And it will be upon this basis that Jesus grants his disciples the authority to make disciples. 
We see this sacred mantle delivered by Christ in verses 19–20. Jesus says:
Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.
This monumental mission has traditionally been called the Great Commission. Notice that the apostles, who will go on to become the very foundation of the church, are not given a mission to be mercenaries who create converts by force. They’re not called to be vigilantes of law and order who wield the sword of retributive justice. And, they’re not called to obtain political power in order to overthrow the Roman Empire. No, the sacred mantle Christ entrusts to his disciples is the divine authority to proclaim the Word of God and shepherd the people of God for the glory of God. 
In short, disciples are entrusted with the privilege and responsibility to make disciples. We accomplish this, first and foremost, by proclaiming the gospel from our neighborhoods to the nations. Salvation comes only through repentance and faith in Jesus Christ, so we must share the good news with everyone in our spheres of contact and influence (Rom 10:13–17). From there, as Jesus explains, disciple making involves baptizing believers in the name of the Father, the Son, and the Holy Spirit. This public profession of faith and identification with the risen Christ and his church, is the believer’s first act of obedience to Christ. This, then, leads to the culminating portion of Christ’s commission, which is teaching believers to continue submitting to Christ’s lordship in all things, with the accompanying promise that he will always be with us. 
The Authority to Affirm Believers
Thus, it is the church of Jesus Christ, with her Lord as the Head, who now represents heaven on earth (Eph 5:23). As Christ’s ambassadors, the church now bears the weight of the sacred mantle, appointed to fulfill a calling of eternal significance. Yet, one of the great challenges found within the responsibility to make disciples is the existence of imposters. Like Satan himself, who disguises himself as an angel of light, there are imposters in this world who claim to be genuine believers in Jesus Christ, and fellow representatives of heaven, but are not (2 Cor 11:14–15). Jesus warned us of these people and provided the criteria by which to discern their true spiritual identity (Matt 7:15–20).
It is for this reason that the church has also been given the authority to affirm true believers, which we find prescribed in Matthew 16.

Another expression of the Immanuel Principle is our hope of our eternal residence with God in heaven; God himself is our eternal dwelling. Between Eden and the Incarnation, the Immanuel Principle was God’s intent, as evidenced in his appearances to man through OT theophanies. Through these appearances we see Christ Himself, manifested through revelations and visions. The OT theophanies reveal to us the God the promises of the onewho would come and dwell with us.

Introduction:  The Immanuel Principle
If we tend to think of “Immanuel: God with us” mostly at Christmas, a deeper study will show it to be a core concept throughout Scripture. As some have explained: ‘The Immanuel Principle’ is God’s intent to be with us and His creation. Understanding and appreciating the Immanuel Principle is one of the reasons why we celebrate the Christmas season. Even though Christmas observance is not scripturally mandated, we should celebrate God’s intent for us to know that he is with us through Christ’s incarnation. It is the core of our Christian hope.
The Immanuel Principle is first seen right at the beginning of God’s revelation in the Garden of Eden as God walked and fellowshipped with man in the cool of the evening. When man’s sin broke his communion with God, His still intended to be with us. Through the incarnation he would show Himself to man, to resolve and remove the sin that had necessitated the separation. As God told Moses, “No one can see my face and live” ( Ex. 33:20).
In Christ’s incarnation we would look on Christ and live, in the same way as Israel did when many were bitten by deadly serpents in the wilderness; Moses was instructed to place a serpent made of brass on a pole so any who looked at it would be healed and live (Num 21/Jn 3: 14-16). This anticipates the unmistakable divine providence pointing to the cross of Christ.
Another expression of the Immanuel Principle is our hope of our eternal residence with God in heaven; God himself is our eternal dwelling. Between Eden and the Incarnation, the Immanuel Principle was God’s intent, as evidenced in his appearances to man through OT theophanies. Through these appearances we see Christ Himself, manifested through revelations and visions. The OT theophanies reveal to us the God the promises of the onewho would come and dwell with us.
The God Who Sees Finds Hagar (Gen 16)
In the OT world, Hagar was a least of the least position. As an Egyptian slave woman, and surrogate mother for Abraham’s family at Sarah’s insistence, Sarah came to despise Hagar even though she gave Abraham a son.  Sarah chased Hagar out of the house through her hostile treatment. Gen 16:7 tells us, “The angel of the LORD” went and found her by a spring of water in the desert wilderness.
The Angel of the LORD asked her a question: “Where are you coming from, and where are you going?” The Angel also promised, “I’ll  give you offspring unable to be numbered,” beginning with the child she was now carrying.  Only God Himself could make such a promise.
The text reveals no fear in Hagar of this Angel; the conversation with Him appears quite normal to Hagar. He appeared ordinary to Hagar, much as Christ in His incarnation “has no majesty or beauty that He would stand out” (Isa 53).  During his earthly ministry, people spoke with the Christ, the God-man, “as a man speaks with his friend.” The Gen. 16:13 account tells us Hagar called the name of the LORD who spoke to her “El Roy,” that is, “You are a God of seeing,” for she knew, “Truly here I have seen him who looks after me.”
While the omnipresent Father sees and knows all, He wants us to know that He knows and sees. It is the Incarnate Christ who tells us, “My sheep hear my voice, and I know them, and they follow me” (John 10:27). As Hagar said, “I have seen him who sees me.” God sees us as “in Christ.” God cares for us in the Person of Christ, who loved us and gave Himself up for us” ( Eph. 5:2).
Jacob Wrestles with God…and Wins (Gen 32)
If God’s appearance to Abraham (in Gen 18, the promised birth of Isaac to Sarah) reveals a God and Savior who keeps His promises, the appearance of Christ to Jacob even more clearly reveals a Savior who shows us God, not only in His holiness, but in His mercy.
Jacob had run from Esau, his brother, having deceived their father to steal Esau’s birthright.  He had gone to his relative Laban in a far country. Eventually, he wore out his welcome there, too, both men agreeing to set up a pile of stones that neither would by-pass, to harass each other. Jacob was anticipating the reunion with Esau, going so far as to prepare for battle by dividing his family and possessions into two separate caravans.
In this fearful mood, Jacob would encounter the pre-incarnate Christ.  Having sent even his wives away, Jacob spent the night alone. As the Scripture tells us, he wrestled all that night with “a man,” a physical confrontation with an incarnate being, of some sort. The two fought to a draw, eventually the Christ- figure damaging Jacob’s thigh socket to break free from his grip.
Even then, Jacob demanded God’s blessing and received it. Christ changed Jacob’s name to Israel saying, “You have striven with God, and have prevailed.” We too have prevailed with God, through the Person of Christ. Later, Jacob summed up the encounter, “I have seen God face to face, and yet my life has been delivered.”
In addition to Christ’s encounter with Hagar that revealed Him to be the one who cares for us, Jacob’s encounter with Christ reveals Him to be the One who shows us God and yet we live, not just in this lifetime but forever.  As Christ said, “Have I been with you so long, and you still do not know me? Whoever has seen me has seen the Father” (John 14:9). In the person of Christ, we see God, and since Christ paid the penalty for our sin we receive life.
Manoah’s Barren Wife: The Sacrifice for Sin that Saves (Judges 13)
In biblical history, as man’s sin deepens, The Immanuel Principle becomes more essential, and in the case of Manoah’s wife, more detailed. While many OT theophanies can leave out details that render the historic account somewhat ambiguous, perhaps no theophany reveals more about the incarnate Christ than this, to Manoah’s wife. During the time of the Judges, Israel had again fallen into great sin, and God had again sent the Philistines to draw them back to Himself.
Manoah was from the tribe of Dan; his wife was barren. Judges 13: 3 tells us the Angel of the LORD appeared to her alone with a message: “You shall conceive and bear a son.” If this rings familiar, recall Isa 7: 14 and Luke 1:31, both foretelling the virgin birth of Christ. Manoah’s wife was instructed to commit to the Nazarite vow of no alcohol or eating unclean animals, as this son would “begin to save Israel from the Philistines,” to save Israel from the consequences of their sin.
This too would find a greater Immanuel Principle fulfillment. As a virgin, Mary would bear a son, and was told to call His name Jesus, for He would fully “save His people from their sins.” After a while, it occurred to Manoah this Angel of the LORD was God Himself, for he said to his wife, “We shall surely die, for we have seen the LORD.”
But her response was insightful, and theologically brilliant. She replied: “If the LORD had meant to kill us, he would not have accepted a burnt offering and a grain offering at our hands, or shown us all these things, or now announced to us such things as these” (13: 23). She knew about the purpose of sacrifices, what Isaiah would also tell Israel hundreds of years later, of the Incarnate Christ on the cross, “He shall see the anguish of His soul, and be satisfied.” Christ was the intent and fulfillment of all the OT sacrifices, the one sacrifice that would fully satisfy the Father.
After the construction of the Tabernacle, and later the Temple, the theophanies would largely cease, for God was dwelling among them.  It would take the Incarnation, that greatest of miracle of all, to show us all that God intended us to know about his dwelling with us.
Before the birth of Jesus, an angel of the Lord appeared to Joseph in a dream saying:
“Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins. All this took place to fulfill what the Lord had spoken by the prophet: “Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel” (which means, God with us) (Matt 1: 20).
The incarnation of Christ demonstrates the fullness of God coming to his people to dwell with them. Jesus assures all who believe:
“My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand. I and the Father are one” (John 10:27-30).
Today God is dwelling with us by His indwelling Spirit. And one glorious day, Christ will return to earth, to raise the dead with the living, “and so we will always be [dwell] with the Lord” (I Thes 4).

We are to seek to live transformed lives and to have our minds informed not by what other people are doing in the secular culture, not by what is deemed acceptable in television episodes or movie scenes of extramarital sex or by homosexual relationships, but we are to have our minds informed by the Word of God. I know of no other antidote for us to heal our sick souls in the midst of this crisis.

In the early years of the 1950s the phenomenon of broadcast television was beginning to sweep America. In these early days, however, it was still a small minority of American households that proudly owned a television set. At this time, a ban was executed by the networks prohibiting the use of the word “virgin” in television broadcasts. The censorship of this word was explained in light of the term’s close connection to matters of sexuality. So sensitive were the original producers of television towards offending the ethics and mores of the American public that words as seemingly harmless as the word “virgin” were banished from the airwaves in order to keep at arm’s length all possible sexual innuendos.
Obviously, we have come a long way from the days of Ozzie and Harriet and the dawn of television broadcasting. However, since that time, the American culture has gone through its most radical cultural revolution in its history. The cultural revolution of the decade of the sixties contained within it a major cultural upheaval with respect to sexual mores. The old taboos against premarital and extramarital sexual relationships were destroyed by the new sex ethic. The new sex ethic was heralded by social scientists such as Alfred Kinsey and later by the Chapman Report and other chroniclers. What society now accepted in practice and in the arts showed a dramatic shift from an earlier time when chastity was regarded as a virtue. Every aspect of the media, in terms of cultural expression, made massive use of the new morality. Today one can hardly read a novel, watch a television program, see a movie in the theater, or even look at the advertisements in magazines and in stores without being acutely aware of this radical shift. Sex is the number-one seller for every conceivable sort of consumer product from razor blades to automobiles. If it’s sexy, it sells.
The cultural revolution brought in its wake a completely different climate with respect to casual sex, extramarital sex, and, in more recent times, homosexual practices. This new climate has produced a level of erotic stimulation that no generation in human history has had to deal with in the past.
Because of this shift in cultural acceptability, young people particularly are bombarded every single day of their lives with every conceivable sort of erotic stimulation. Of course, as long as there have been men and women, there have been biological urges and sexual appetites to deal with in terms of seeking to live chaste and virtuous lives. There is a sense in which fallen humanity has always had to struggle with the erotic impulses of the human heart, but at the same time there has been a massive escalation of temptation brought in the wake of the explosion of erotic stimulation in our day.
The advent of the computer and the use of the Internet has rapidly increased this escalation. Though I am technologically challenged—
