2 Peter 1:19

1:19 Moreover, we possess the prophetic word as an altogether reliable thing. You do well if you pay attention to this as you would to a light shining in a murky place, until the day dawns and the morning star rises in your hearts.

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.
