2 Peter 1:10-12 ESV
Therefore, brothers, be all the more diligent to confirm your calling and election, for if you practice these qualities you will never fall. For in this way there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ.
Therefore I intend always to remind you of these qualities, though you know them and are established in the truth that you have.
