2 Peter 3:16-18 New American Bible (Revised Edition) (NABRE)
16 speaking of these things[a] as he does in all his letters. In them there are some things hard to understand that the ignorant and unstable distort to their own destruction, just as they do the other scriptures.
V. Final Exhortation and Doxology[b]
17 Therefore, beloved, since you are forewarned, be on your guard not to be led into the error of the unprincipled and to fall from your own stability. 18 But grow in grace and in the knowledge of our Lord and savior Jesus Christ. To him be glory now and to the day of eternity. [Amen.]
