2 Peter 1:12-15 NKJV

12 For this reason I will not be negligent to remind you always of these things, though you know and are established in the present truth.
13 Yes, I think it is right, as long as I am in this tent, to stir you up by reminding you,
14 knowing that shortly I must put off my tent, just as our Lord Jesus Christ showed me.
15 Moreover I will be careful to ensure that you always have a reminder of these things after my decease.
