Charles Spurgeon Commentary 2 Peter 3:1

"This is now, beloved, the second epistle that I write unto you; and in both of them I stir up your sincere mind by putting you in remembrance;" — 2 Peter 3:1 (ASV)

This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance:

The purest minds need stirring up at times. It would be a great pity to stir up impure minds. That would only be to do mischief; but pure minds may be stirred as much as you please, and the more the better. There are hallowed memories in the minds of all Christians; but those memories are apt to lie asleep, and it is well to ring the alarm bell, and wake up all the memories within the believer's heart, even as Peter did when he wrote, I stir up your pure minds by way of remembrance.
