I am writing this letter to you in order to help you remember what the holy prophets said and what our Lord and Savior commanded.

3  2 Peter 3:1-2

3 This letter that I am now writing to you whom I love, is the second letter that I have written to you. In both these letters I have reminded you about the things you already know, in order that I may stimulate/cause you to think sincerely about those things. 2 I want you to remember the words that were spoken by the holy prophets {that the holy prophets spoke} long ago, and also to remember what our Lord and Savior commanded, things that we, your apostles, told you about.
