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 2:20

2:20 For if after they have escaped the filthy things of the world through the rich knowledge of our Lord and Savior Jesus Christ, they again get entangled in them and succumb to them, their last state has become worse for them than their first.
