2 Peter 1:8-10

8 For if you have these qualities in abundance, they keep you from being barren and unfruitful in the knowledge of our Lord Yeshua the Messiah.

9 Indeed, whoever lacks them is blind, so shortsighted that he forgets that his past sins have been washed away.

10 Therefore, brothers, try even harder to make your being called and chosen a certainty. For if you keep doing this, you will never stumble.
