2 Peter 3:16-18

3:16 speaking of these things in all his letters. Some things in these letters are hard to understand, things the ignorant and unstable twist to their own destruction, as they also do to the rest of the scriptures. 3:17 Therefore, dear friends, since you have been forewarned, be on your guard that you do not get led astray by the error of these unprincipled men and fall from your firm grasp on the truth. 3:18 But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the honor both now and on that eternal day.
