One writer has identified five major motifs in 1 Peter. These are the believer's behavior, the believer's unfair circumstances, the believer's deference, the believer's motivation by Christ's example, and the believer's anticipation of future glory. These are certainly important emphases in this epistle.
Putting these together he has stated the message of 1 Peter as follows. "The behavior of believers when they encounter unfair circumstances reflects a spirit of deference in all relationships as they follow Christ's example and anticipate future glory."8
This is a very fine statement of what the Holy Spirit has said to us through Peter in this epistle. However, I would add one more important motif. It is the believer's resource of God's grace. This is not an incidental motif but one that underlies all of what Peter called on his readers to do. We must understand and apply what he wrote about God's grace as our resource to follow his exhortations.
It seems to me that Peter stated the message of this epistle clearly: stand firm in the true grace of God (5:12).
The subject of the letter therefore is the true grace of God. Grace is the key word in the argument of this epistle. In each case the word "grace"occurs in the practical rather than in the doctrinal part of each section of the letter. Throughout 1 Peter the fact of God's grace was in Peter's mind as crucial to the believer's practice. How does one explain God's grace? Grace means both undeserved favor and divine enablement.
The main purpose of this epistle was to strengthen the readers so they would persevere through their persecution with the right attitude. Peter did this by showing that God's grace provided all they needed for strength. In a larger sense, the purpose is to help Christians know how to live as aliens in the world.
This epistle reveals above all else that God's grace is sufficient for all our needs. We could write over this whole book: 2 Corinthians 12:9. Notice five things Peter reminds us about God's grace. Let's trace the references to grace though 1 Peter.
1. Grace proceeds from God. God in His grace has chosen us (1:1). Now we need to realize God's grace in its fullest measure in our experience (1:2).
2. Grace produces confidence. The prophets foretold God's grace (1:10). The advents of Jesus Christ supplied God's grace (1:13). It came into the world at His first advent through His sufferings and death. It will come into the world again at His second advent through His glorification. This pattern gives us confidence. God has united us with Christ. As He suffered once, we suffer now. As certainly as He will receive glory in the future, we too will experience glorification in the future. We need to remember our hope.
3. What proclaims God's grace is our conduct (2:19-20). The Christian's conduct in trying and difficult circumstances manifests God's grace in a human life. The submissive conduct of servants whose masters are persecuting them manifests God's grace. The submissive conduct of wives whose antagonistic husbands are persecuting them manifests grace. The submissive conduct of husbands whom unbelievers are persecuting manifests grace. The husband demonstrates his submission to God by treating his wife as a fellow heir of God's grace (3:7). Our patient endurance of trials displays our submission to God's will. Thus our conduct manifests God's grace. Sometimes we marvel at the ability God gives his persecuted saints to endure. We say, "How can he (or she) do it?"
4. Grace perfects character. Grace is the source of service (4:10). Grace is also the source of humility (5:5). An attitude of humility manifests itself in service of others. God's grace is the secret of both the attitude and the activity. Jesus established "the order of the towel"by washing the disciples' feet (John 13).
5. Grace promotes courage (5:10). We need courage to resist the devil (5:8-9). God's grace gives us strength to defend ourselves against his attacks.
The epistle exhorts us to stand firm in this grace. This is Peter's appeal to us.
When God tries our faith, we need to remember that we have an adequate source of strength in God's grace.
When our faith is trembling, we need to remember that we have an adequate source of confidence in God's grace.
When our circumstances are difficult we need to remember that we have an adequate source of conduct in God's grace.
When we suffer for conscience's sake we need to remember that we have an adequate source of character in God's grace.
When assaulted by the adversary we need to remember that we have an adequate source of courage in God's grace.
We stand firm in the true grace of God when we respond to suffering for Christ's sake as Peter directed us. God's grace is what we need to rely on as we commit ourselves to continue to walk in the will of God. Trust and obey!
