The first of two letters from Peter to God’s chosen people in Pontus, Galatia, Cappadocia, Asia, and Bithynia (in modern-day Turkey) (Part 1): 1 Peter 1–3

Peter instructed the believers to love each other because they now had eternal life from the word of God, which lasts forever:

1 Peter 1:25 And that word is the Good News that was preached to you.
