2 Peter 3:14-16

14 Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless, 15 and regard the patience of our Lord as salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you, 16 as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction.

Here Peter goes on to say that since we are eager for His coming, we ought also to be at peace with God and to live blamelessly (without grumbling about things, Phil. 2:14-15). And remember that our Lord is patiently waiting for people to repent and be saved; and that is why His coming may seem to take long.

Peter here mentions the Apostle Paul, who wrote on this same subject of His coming; that he was given wisdom from the Lord to understand these hard topics. But Peter wanted them to know that false prophets (particularly those who are “untaught” or have been instructed wrongly) have distorted Paul’s teaching on this subject, and also on all Scriptures. (Today there are many seminaries that are quite liberal and distort the truth of Scripture, so that those who attend graduate without knowing the truth.)
