2 Peter 3:15-16

15 and regard the patience of our Lord as salvation. So also our beloved brother Paul wrote to you according to the wisdom given him,
16 speaking of this as he does in all his letters. There are some things in them hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other scriptures.
