Scriptural Inspiration and Authority

Scripture is given so that the “man of God may be complete” (2 Tim. 3:17). The word that is translated “complete” (Greek artios) means “fit, complete, capable, adequate, sufficient.” Paul says that God’s Word is complete and sufficient so that we can be men and women of God, “equipped for every good work” (v. 17). The word that is translated “equipped” (Greek exartizo) was used to describe a wagon that was completely outfitted for a long journey or a rescue boat that was sufficiently prepared for its mission. It is a wonderful picture of both the Christian’s and the church’s relationship to Holy Scripture.

The church is at a watershed moment. Much like the church of a hundred years ago, in which parties divided over the doctrine of biblical inspiration and inerrancy, we are at a crossroads. This time, rather than biblical inerrancy, the division is over the Bible’s authority and sufficiency. The predominant worldviews in our culture firmly oppose the Christian worldview. We live in a post-Christian society. So the pressure exerted on both the individual Christian and the church to abandon biblical doctrine, especially along the lines of biblical sexuality, is immense. Therefore, the issue of biblical authority and sufficiency is the continental divide of our generation. I believe that we will see a great rebellion and apostasy in our lifetime because of a fundamental rejection of this doctrine (Matt. 24:11–14; 2 Thess. 2:3; 2 Tim. 3:1–8). Many who claim the name of Christ have already begun following after the world rather than holding fast to the “faith that was once for all delivered to the saints” (Jude 3).
The locus classicus text that speaks to the Bible’s inspiration and authority is 2 Timothy 3:16–17: “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.” Paul makes a most definitive statement: every word of Scripture is breathed out by God. In other words, as B.B. Warfield used to say, “When Scripture speaks, God speaks.” For that reason, Scripture is authoritative on every subject that it addresses. We should add that this means that Scripture is the final authority, and no other authorities in this world even come close to it. For what can stand against God’s Word (Isa. 40:8)? In addition to seeing Scripture’s inspiration and authority in this text, Paul presses us to understand Scripture’s sufficiency. Scripture is given so that the “man of God may be complete” (2 Tim. 3:17). The word that is translated “complete” (Greek artios) means “fit, complete, capable, adequate, sufficient.” Paul says that God’s Word is complete and sufficient so that we can be men and women of God, “equipped for every good work” (v. 17). The word that is translated “equipped” (Greek exartizo) was used to describe a wagon that was completely outfitted for a long journey or a rescue boat that was sufficiently prepared for its mission. It is a wonderful picture of both the Christian’s and the church’s relationship to Holy Scripture.
Scripture is all that we need to be “outfitted” for the Christian life. Scripture is all we need for “righteousness.” Scripture is all that the church needs to faithfully serve and honor Christ and advance the kingdom.

Serving Hostile Authorities

Written by Grant R. Castleberry |
Sunday, October 3, 2021
We must make every effort to serve transcendently. By this I mean that we must be God-centered. Our ultimate goal is His honor. Our greatest work is to obey Him. Our ultimate joy is to know Him. We might serve under hostile authorities, but our greatest authority is our kind and merciful Father. 

Increasingly, in a post-Christian world, Christians will serve in positions of influence under leaders who outright reject the Christian faith. Though our culture rejects the Lord Jesus, I believe that God will continue to providentially place Christians in positions of influence. The question that we all must be able to answer is, What is the Christian strategy for work in a post-Christian world? Let me offer three principles that form a biblical strategy for serving under hostile authorities.

Serve Virtuously
First, we must strive to serve virtuously. The Apostle Paul makes a fascinating statement at the end of his list of the fruit of the Spirit in Galatians 5:23. He says, “Against such things there is no law.” In other words, virtue is not contraband. No society, regardless of its immorality and godlessness, has banned the greatest of all virtues: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control (vv. 22–23). In a world dead-set on moral decadence, Christians possess both the spiritual ability and the moral mandate to display true godliness. In many instances, we will be the only Bible people will ever read. So, our lives must attest to the holy God we worship. As Jesus commands us, “Let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven” (Matt. 5:16). In Luke’s gospel, John the Baptist is asked by some new disciples how they can continue serving in their current secular positions:
Tax collectors also came to be baptized and said to him, “Teacher, what shall we do?” And he said to them, “Collect no more than you are authorized to do.” Soldiers also asked him, “And we, what shall we do?” And he said to them, “Do not extort money from anyone by threats or by false accusation, and be content with your wages.” (3:12–14)
It is telling that John the Baptist’s imperatives are all moral. His disciples were not to resign their positions. Rather, they were to serve virtuously.
