Albert Barnes Commentary 2 Peter 3:11

"Seeing that these things are thus all to be dissolved, what manner of persons ought ye to be in [all] holy living and godliness," — 2 Peter 3:11 (ASV)

Seeing then that all these things shall be dissolved. Since this is an undoubted truth.

What manner of persons ought you to be in all holy conversation and godliness. In holy conduct and piety. That is, this fact ought to exert a deep and abiding influence on us, to induce us to lead holy lives. We should feel that there is nothing permanent on the earth; that this is not our abiding home; and that our great interests are in another world.

We should be serious, humble, and prayerful; and should make it our great object to be prepared for the solemn scenes through which we are soon to pass. A habitual contemplation of the truth, that all that we see is soon to pass away, would produce a most salutary effect on the mind.

It would make us serious. It would repress ambition. It would lead us not to desire to accumulate what must so soon be destroyed. It would prompt us to lay up our treasures in heaven. It would cause us to ask with deep earnestness whether we are prepared for these amazing scenes, should they suddenly burst upon us.
