2 Peter
Peter tells us clearly in 3:1-2 that this, his second epistle, is written to the same churches for the same reasons as the first. That is, he is writing to remind them to remain faithful to and grow in the things they know and are commanded to obey, those things of God given to them by both the holy prophets of old and by Christ and his apostles. This was urgent, first because this true knowledge was under attack by teachers of a false “knowledge” that was the mere speculation of sensual unprincipled men (cf. Acts 20:29-30). Secondly, it was urgent because Peter knew his death was imminent, and by writing to them once again they would always be able to call these things to mind (1:14-15), as can we also through the word written.
