Schaeffer says our love must be observable, something others can see. Observable love often requires saying sorry and asking for forgiveness—with a spouse, a friend, a child, a parent, or another person or group we’ve wronged. This is simple, but it won’t be easy. In my experience, it takes great strength of character to say, “I’m sorry. I was wrong. Will you forgive me?”

Editors’ note: Taking the advice of C. S. Lewis, we want to help our readers “keep the clean sea breeze of the centuries blowing through our minds,” which, as he argued, “can be done only by reading old books.” To that end, our Rediscovering Forgotten Classics series surveys some forgotten Christian classics that remain relevant and serve the church today.
I tend to tune out social media controversies and negative online comments. It’s generally a good course of action given the storms of shock and outrage about nearly everything on any given day. Even attempts at good-faith responses sometimes fan the flames.
Avoiding such storms works well because of the distance the internet provides. But when Henry, a real-life friend of mine, objected on social media to something I was personally involved with, it raised a different set of questions. Since the critique was on social media, should I respond there? Should I give a long, nuanced reply, sure to be read by few? Should I say something punchy, sure to get everyone’s attention? Should I ignore it? As Christians, how can we learn to disagree well, especially with other Christians?
In 1970, Francis Schaeffer, one of the most astute apologists of the 20th century, published The Mark of the Christian. I first read the book about 50 years ago, and it continues to shape how I think about encounters like the one with my friend. It’s a brief book; you can read it in about an hour. Yet it may carry more weight today than at any time in the last half-century because it reminds us of the importance of loving our neighbor and being able to disagree well—vital skills in an increasingly polarized age.
Two Passages in John
The Mark of the Christian is Schaeffer’s meditation on two passages in John’s Gospel. He begins with John 13:34–35: “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.”
Schaeffer marvels at Jesus’s words:
In the midst of the world, in the midst of our present dying culture, Jesus is giving a right to the world. Upon his authority he gives the world the right to judge whether you and I are born-again Christians on the basis of our observable love toward all Christians. . . .
In other words, if people come up to us and cast in our teeth the judgment that we are not Christians because we have not shown love toward other Christians, we must understand that they are only exercising a prerogative which Jesus gave them. And we must not get angry. . . . We must go home, get on our knees and ask God whether or not they are right. (22–23)

Some examples of the way that the self-discipline of choosing the right perspective empowers godly character. Forgiveness: refusing to demand that another person treat me perfectly when God has forgiven a thousand times more imperfections in me. Humility: recognizing that God and others are actually the ones responsible for the achievements in my life. Contentment: realizing that God has already provided everything I need for my present happiness. Patience: realizing that others’ imperfections that inconvenience me provide the opportunity to show them Christ-like unconditional love.

It has been said, probably mostly in the manufacturing world, that imitation is the highest form of flattery. I think there is truth in that statement—at least when it comes to how we pattern our life. The highest of all compliments to another is probably having a passion to be like him or her. When it comes to thanking Jesus for his unfathomable grace and love for me, I’m not sure anything would mean more to him than passionately seeking to BE LIKE HIM. This episode is the third in our study of the astonishing first chapter of 2nd Peter in which God tells us that his divine power makes it possible for us to do that very thing–become partakers of his divine nature, escaping the corruption of our sinful desires. Today, we examine step 3 for accessing that divine power.
Let’s review what we have seen in this text, Peter 1:3-8, so far. We noted last week that this 3-step process of becoming Christ-like, ends with the promise that continuing this process of growing into Christ-like character guarantees that our lives in Christ will NOT BE ineffective or unfruitful. Verse 8: For if these qualities are yours and are increasing, they keep you from being INEFFECTIVE or UNFRUITFUL in the knowledge of our Lord Jesus Christ.
We noted that Peter explains this three-step process beginning in verse 3: His divine power has granted to us all things that pertain to life and godliness, through the KNOWLEDGE of him who called us to his own glory and excellence. Step #1 in being transformed into the likeness of Christ is KNOWING him well, personally, gazing upon his gory and excellence. Paul sends us the same message about how we are transformed writing, And we all…. BEHOLDING the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit (2 Cor 3:18).
Last week, we examined step #2 in this process of accessing the power of the Holy Spirit to become Christ-like. Verse 4: by which he has granted to us his precious and very great promises, SO THAT THROUGH THEM you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire. Why are God’s great and precious promises a key to a Jesus-like heart? Perhaps it is because our self-centered preoccupations, compulsions, fears, and anxieties so take over our hearts that they push the Christ-like heart commitment to love God and others to the side. However, when I can transfer all those self-centered preoccupations to God, knowing he will take care of whatever I fear or worry about, I am emotionally free to focus on loving—God and others. For example, if my heart is filled with anxiety over whether I have the money to pay my mortgage, I will not be able to concentrate on listening well or notice another’s needs. I am too preoccupied with worry. But claiming God’s promise in Phil 4:19, My God will supply every need of yours according to his riches in glory in Christ Jesus sets my heart free to focus on others.
So, step #1 in this pathway to Christ-like heart attitudes is abiding in Christ, the Vine, walking with him and being transformed as we see his glory and moral excellence. Step #2 in this pathway to Christ-like attitudes is walking daily by faith—trusting in his great and precious promises to provide all we need. Today we come to step #3: Verse 5: MAKE EVERY EFFORT to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control, with steadfastness, and steadfastness with godliness, and godliness with brotherly affection, and brotherly affection with love. Step #3 in this pathway to Christ-like heart attitudes is to be intentional about building Christ-like character. That is what Peter commands. Make every effort to build a golden chain of virtues.
Let’s look at this list of virtues.
Faith
The beginning virtue, FAITH, refers back to step 2–living daily by claiming the promises of God. The foundation of Peter’s golden chain is trusting God’s promises, which frees our hearts to be OTHER-focused instead of SELF-focused. Escaping from desires ruling my heart that exhibit preoccupation with ourselves is only possible by trusting Jesus to worry about all those concerns SO WE DON’T HAVE TO. Let’s consider how this works.

If the fear of being rejected is dominating my heart, I will not be sensitive to the other’s needs to be affirmed and valued, but unconsciously maneuver to make sure I am seen in the best light. However, if the truth of Zephaniah 3:17 captures my heart, reassuring me that I am deeply loved by God, such confidence will drive out my self-centered need to feel valuable, empowering me to love others well by affirming THEM. The Lord your God is in your midst, a mighty one who will save; he will rejoice over you with gladness; he will quiet you by his love; he will exult over you with loud singing.
If my heart entertains secret doubts about God’s goodness, I will not want to come into his presence. Hebrews 11:6 says, Whoever would draw near to God must believe that he exists and that he rewards those who seek him. But if I claim Ps 34:10, I will run to God. Even the young lions suffer want and hunger; but those who seek the Lord lack no good thing.
If God has ordained circumstances that are painful for me, filling my heart with doubts about his love, rebellion may creep into my heart. But if I claim God’s promise in Rom 8:31-32, rebellion flees from my heart (momentarily)! If God is for us, who can be against us? He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things? Then my heart is free to love God in his love language, “If you love me keep my commandments” (Jn 14:5).
If the fear of being alone overpowers my heart, I will easily compromise my moral convictions to fit in. The potential pain of being left out drives me. But my heart is freed from this fear when I lean upon Is 41:10. Do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my right hand. I can take a stand for righteousness that will also help others in the room do what is right.
When my heart is empty and I feel unsatisfied, like trying to follow Jesus is not worth it, discontent, and envy of others can take over. But when I lean on the truth of Psalm 37:4, Delight yourself in the Lord, and he will give you the desires of your heart, my heart is free to take my empty tank to God to fill.
When I am at the end of my rope, having asked God over and over to change a situation which causes a lot of pain but he refuses to do so, distrust can take over my heart. In such moments, I need to rely upon verses like, I Pet 5:7, You can throw the whole weight of your anxieties upon him, for you are his personal concern.

Mary models the right posture towards God with her willingness to trust him because he is good and his word is true. While she had significant questions, she did not allow them to keep her from receiving what God had said. This was an overwhelming day for Mary. Indeed, this faithful monotheist worshiper of Yahweh had to allow God’s Word to stretch her faith beyond what she had already understood from his Word. 

Christmas provides numerous opportunities to learn more about God and his great plan of salvation. First, we can consider Christ’s unique birth as shepherds come to bear witness and the angels sing his praise (Luke 2:20). Second, we can understand more of who Jesus is by tracing the many promises God has made throughout Scripture and how they are all fulfilled in Christ. Often, the connections to Christ are called “scarlet threads” because God’s promises run throughout Scripture and intertwine with one another to be fulfilled in Jesus Christ. Still more, we learn doctrinal truths at Christmas too. One of the most important revelations at Christmas is the fact that the one God is Father, Son, and Holy Spirit.
Wonderfully, Christmas calls the church to look back and see the Triune nature of God vaguely revealed in the Old Testament, but this more intimate and personal knowledge of him is not manifested until the Word becomes flesh; the only begotten Son comes from the Father’s bosom to unite with humanity.
Coming Into View
The first full revelation of God as Father, Son, and Spirit is given to the young virgin Mary who receives this fuller knowledge of his nature by faith (Luke 1:26–38). It is amazing how much Mary was expected to process at this revelation. Consider three things.
First, the angel declares to Mary that she will conceive and have a son as a virgin, a word that harkens back to Isaiah 7:14. Second, the promised child is declared to be great and the Son of the Most High, language that combines 2 Samuel 7:14 and Psalm 2. Third, the Son will be given the throne of David and will reign forever, also a reference to the promise God made to David in 2 Samuel 7:14 that God would be like a father to the forever king and that the forever king will be like a son to him.
These three declarations to Mary help us appreciate God’s progressive revelation as the promised son and king is now known as the Son of God. The Son of the Most High would add to himself humanity so that he could be the forever king promised in 2 Samuel.
But How Much Did Mary Know?
It is not clear how much Mary understood this revelation into the nature of God, nor how her commitment to worshiping one God was being reshaped. However, it is clear that she received it by faith while seeking more understanding. With faith, she protests, “How will this be, since I am a virgin?” (Luke 1:34). In comparison to her uncle Zechariah’s request for confirmation when he was told that in his old age he would have a son (Luke 1:18), Mary’s response is of a different type. While Zechariah was rebuked and made mute for his question that revealed doubt, Mary does not ask for proof. Rather, she asks an honest and important question.
