2 Peter 1:12–15

12 Therefore I intend always to remind you of these qualities, though you know them and are established in the truth that you have. 13 I think it right, as long as I am in this body, to stir you up by way of reminder, 14 since I know that the putting off of my body will be soon, as our Lord Jesus Christ made clear to me. 15 And I will make every effort so that after my departure you may be able at any time to recall these things.
