3:1 second epistle. This shows that Peter’s second epistle was addressed to the same general audience as the first. They, therefore, would already have knowledge of what he had written before, but now he was giving them additional instruction in light of the difficult days coming and his own approaching demise. The Lord’s return might even have been very soon, as far as they knew, for it was always imminent. Surely Peter’s message of the first century is even more needed and appropriate today in the twenty-first century.

3:1 pure minds. It is vital that Christians in the last days “stir up” their minds, not just their emotions, but exactly the opposite seems to be happening today.

3:1 remembrance. See also II Peter 1:13. It is easy to forget the more important truths when we are being bombarded continuously by the trivial.
