Matthew Henry Commentary 2 Peter 1:12-15

"Wherefore I shall be ready always to put you in remembrance of these things, though ye know them, and are established in the truth which is with [you]. And I think it right, as long as I am in this tabernacle, to stir you up by putting you in remembrance; knowing that the putting off of my tabernacle cometh swiftly, even as our Lord Jesus Christ signified unto me. Yea, I will give diligence that at every time ye may be able after my decease to call these things to remembrance." — 2 Peter 1:12-15 (ASV)

We must be established in the belief of the truth, so that we are not shaken by every wind of doctrine; and especially in the truth necessary for us to know in our day, what pertains to our peace and what is opposed in our time.

The body is merely a tabernacle, or tent, of the soul. It is a humble and movable dwelling. The nearness of death makes the apostle diligent in the work of life.

Nothing can give such composure in the prospect of death, or in the hour of death, as knowing that we have faithfully and simply followed the Lord Jesus and sought His glory. Those who fear the Lord talk of His loving-kindness. This is the way to spread the knowledge of the Lord; and through the written word, they are enabled to do this.
