2 Peter 3:15-16

And consider the patience of our Lord [His delay in judging and avenging wrongs] as salvation [that is, allowing time for more to be saved]; just as our beloved brother Paul also wrote to you according to the wisdom given to him [by God], speaking about these things as he does in all of his letters. In which there are some things that are difficult to understand, which the untaught and unstable [who have fallen into error] twist and misinterpret, just as they do the rest of the Scriptures, to their own destruction.
