2nd Peter 1:13

10 Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble.

11 For thus will be richly supplied to you the entrance into the eternal kingdom of our Lord and Savior, Jesus Christ.

12 Therefore I will not be negligent to remind you of these things, though you know them, and are established in the present truth.

13 I think it right, as long as I am in this tent, to stir you up by reminding you;

14 knowing that the putting off of my tent comes swiftly, even as our Lord, Jesus Christ, made clear to me.

15 Yes, I will make every effort that you may always be able to remember these things even after my departure.

16 For we did not follow cunningly devised fables, when we made known to you the power and coming of our Lord, Jesus Christ, but we were eyewitnesses of his majesty.
