2 Peter 3:14-17

So, beloved, since you are looking forward to these things, be diligent and make every effort to be found by Him [at His return] spotless and blameless, in peace [that is, inwardly calm with a sense of spiritual well-being and confidence, having lived a life of obedience to Him]. 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. Therefore, [let me warn you] beloved, knowing these things beforehand, be on your guard so that you are not carried away by the error of unprincipled men [who distort doctrine] and fall from your own steadfastness [of mind, knowledge, truth, and faith]
