These two letters of Peter were written to first century Christians needing clear instruction about their faith in Christ. By the leading of the Holy Spirit, these letters have remained timeless. No matter which period of church history one might want to discuss, these letters fit well. Christian character, holiness, the Day of Judgment, and the Second Coming are always important to the proper development of a Christian's faith.
“The words of Luther concerning this text have been cited many times: ‘This is a strange text and certainly a more obscure passage than any other passage in the New Testament.” (1 Peter 3:20)
“‘a royal priesthood.’ By royal priesthood he meant a group of priests in special service of the king, that is, God.” (1 Peter 2:9)
“God did not only fore-see that he would send Christ, but he fore-planned it. That very plan entailed a plan to create a people around Christ. His ‘foreknowledge’ involved ‘fore-planning’ or ‘fore-purposing.’ The predestination spoken of here is a corporate predestining of a people called into being by their response to Christ. God foreknew that he would send Christ and save those who accepted him.” (1 Peter 1:2)
“He is not dealing with Christians’ equality with each other, but with the fact that Christians are God’s chosen servants, set apart (‘holy’—see 1:16) by God to offer spiritual sacrifices to him.” (1 Peter 2:5)
“Peter’s idea is a powerful one: Christians are exiles on the earth. Their true citizenship is in heaven.” (1 Peter 2:11)
