2 Peter 1:8

1:8 For if these things are really yours and are continually increasing, they will keep you from becoming ineffective and unproductive in your pursuit of knowing our Lord Jesus Christ more intimately.

2 Peter 1:16

1:16 For we did not follow cleverly concocted fables when we made known to you the power and return of our Lord Jesus Christ; no, we were eyewitnesses of his grandeur.

2 Peter 3:8-9

3:8 Now, dear friends, do not let this one thing escape your notice, that a single day is like a thousand years with the Lord and a thousand years are like a single day. 3:9 The Lord is not slow concerning his promise, as some regard slowness, but is being patient toward you, because he does not wish for any to perish but for all to come to repentance.
