He writes this way in all his letters, speaking in them about such matters. Some parts of his letters are hard to understand, which ignorant and unstable people distort, as they do the rest of the Scriptures, to their own destruction.
The Pauline Epistles by now were the common property of all churches, and the word "all" suggests they were complete. Paul handled Christ's coming in Thessalonians much as Peter does here, yet some things are hard to understand, the man of sin, the apostasy before His coming. But enough is plain and sufficient for perfecting the man of God.
AI summary
Some things in Scripture are obscure and dark, and the ignorant twist them to overthrow those not yet established in the faith, to their own destruction. The remedy is to labor daily to grow and increase in the knowledge of Christ.
AI summary
Paul had written many epistles by this time, all under the same wisdom and Spirit's influence. He speaks in them of Christ's second coming, of mockers and wicked men in the last days, and of mysteries not easily understood, the timing of His return, the manner of His appearing, the resurrection in spiritual bodies, the rapture of the saints.
