2 Peter 3:1

This second epistle, beloved, I now write unto you A new section of the Epistle opens. The "false teachers" recede from view, and the thoughts of the Apostle turn to the mockers who made merry at the delay of the coming of the Lord, to which Christians had so confidently looked forward as nigh at hand. In the stress laid on this being the "secondEpistle" we have a fact which compels us to choose between identity of authorship for both Epistles, or a deliberate imposture as regards the second.

I stir up your pure minds by way of remembrance The word for "pure" is found in Philippians 1:10, the corresponding noun in 1Co 5:8; 2 Corinthians 1:12; 2 Corinthians 2:17. Its primary application is to that which will bear the full test of being examined by sunlight, and so it carries with it the sense of a transparentsincerity. Its exact opposite is described in Ephesians 4:18, "having the understanding" (the same Greek word as that here rendered "mind") darkened. In the "stirring up by way of remembrance" we have a phrase that had been used before (chap. 2 Peter 1:13).
