Passage
You therefore, beloved, knowing this beforehand, be on your guard lest you, having been carried away by the error of unprincipled men, fall from your own steadfastness,
You therefore, beloved, knowing this beforehand, be on your guard lest you, having been carried away by the error of unprincipled men, fall from your own steadfastness,
2 Peter 3:15 and consider the patience of our Lord as salvation, just as also our beloved brother Paul, according to the wisdom given him, wrote to you,
2 Peter 3:16 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.
2 Peter 3:17 You therefore, beloved, knowing this beforehand, be on your guard lest you, having been carried away by the error of unprincipled men, fall from your own steadfastness,
2 Peter 3:18 but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory, both now and to the day of eternity. Amen.
The verse centers on "therefore", "beloved", "knowing", "beforehand", "guard", "lest", "having", and "been". It is saying that the verse draws attention to "therefore" and "beloved", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "as also in all his letters speaking..." into verse 18's "but grow in the grace and knowledge...", so "therefore" and "beloved" belong inside that flow. In 2 Peter context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "beloved" with trust shaped by these words, not by a vague optimism outside the passage.
