2 Peter 1:10

10 Therefore, my brothers and sisters, make every effort to confirm your calling and election. For if you do these things, you will never stumble,

2 Peter 1:15

15 And I will make every effort to see that after my departure you will always be able to remember these things.

2 Peter 1:19

19 We also have the prophetic message as something completely reliable, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts.
