2 Peter 1:12-15 GNTA

12 And so I will always remind you of these matters, even though you already know them and are firmly grounded in the truth you have received.
13 I think it only right for me to stir up your memory of these matters as long as I am still alive.
14 I know that I shall soon put off this mortal body, as our Lord Jesus Christ plainly told me.
15 I will do my best, then, to provide a way for you to remember these matters at all times after my death.
