Purpose of Writing: 3: 1 - 7.
In this chapter Peter provides comfort to Christians by explaining that justice will come soon. Peter reminds the readers the the purpose of writing this letter was to stir up their sincere mind (1: 2, 13). He warns believers that scoffers will come in the last days (3:3). Christians are beloved brothers. They are not professionals but brothers in the family of God. Their memory need to be refreshed and thinking should be stimulated by reminding them of what prophets and apostle already warned. The scoffers would come in the last days following their own lust (1 Tim 4: 1). They pride themselves that they have special knowledge. Those who scoff at the hope of Christ's return, arrogantly overlook the fact that God is the creator and judge of the world. (3:5-6). Just as he once judged the world with the flood, one day God will judge the present world with fire. But they willfully forget the coming judgment. The day of the Lord is a reference to the period when God acts in judgment.
False Teachers are Scoffers:3:8-13.
Peter warns that in the last days, scoffer will come. The “Last days” is a term refers to a period of time from the coming of Christ to our rapture. While it seem to us that Christ's return has been delayed a long time but it is a moment to our Lord. With the Lord one day is as a thousand years and a thousand years as one day (3:8). The Lord is not slow to fulfill his promise but he is patient in love, giving people more time to turn to Christ and be saved (3:9).
God’s Amazing Grace:3:14-18.
Peter exhorts Christians to remain holy and blameless in these days of false teaching. A new world is coming. Since we have the truth of the gospel , we must resist the false teaching and worldly corruption (3:17). The grace saved us will empower us to grow in Christ. The promise of Christ’s return should motivate us to grow in the grace and knowledge of Christ. Growing in the grace and in the knowledge of Christ must go together. Christian life is not lived on auto pilot. Sixteen times the word knowledge is used in this letter. Biblical knowledge is the experiential knowledge. This gives us assurance of God’s saving grace. Those who are born again must remain firm in their faith and appreciate what God is doing in their lives. It is a fight they cannot lose, because God has provided all they need (1:3). Peter encourages believers be on guard against false teachers and fall from their own steadfastness. He wants them to grow in the grace and in the knowledge of our Lord and Savior Jesus Christ (3:18). Do you appreciate God's amazing grace!
