The author identified himself as Simon Peter. Simon Peter was an apostle. He also wrote 1 Peter. Peter probably wrote this letter while in a prison in Rome just before he died. Peter called this letter his second letter, so we can date it after 1 Peter. He addressed the letter to the same audience as his first letter.

Peter wrote this letter to encourage believers to live good lives. He warned them about false teachers who were saying Jesus was taking too long to return. He told them that Jesus was not slow in returning. Instead, God was giving people time to repent so that they would be saved.
