2 Peter 1:10-12

¹⁰Therefore, brothers and sisters, be all the more diligent to make certain about His calling and choice of you; for as long as you practice these things, you will never stumble; ¹¹for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.

¹²Therefore, I will always be ready to remind you of these things, even though you already know them and have been established in the truth which is present with you.
