Commentaries
1:12-15 We must be established in the belief of the truth, that we may not be shaken by every wind of doctrine; and especially in the truth necessary for us to know in our day, what belongs to our peace, and what is opposed in our time. The body is but a tabernacle, or tent, of the soul. It is a mean and movable dwelling. The nearness of death makes the apostle diligent in the business of life. Nothing can so give composure in the prospect, or in the hour, of death, as to know 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 by the written word, they are enabled to do this.
12. Wherefore—as these graces are so necessary to your abundant entrance into Christ's kingdom (2Pe 1:10, 11).
I will not be negligent—The oldest manuscripts read, "I will be about always to put you in remembrance" (an accumulated future: I will regard you as always needing to be reminded): compare "I will endeavor," 2Pe 1:15. "I will be sure always to remind you" [Alford]. "Always"; implying the reason why he writes the second Epistle so soon after the first. He feels there is likely to be more and more need of admonition on account of the increasing corruption (2Pe 2:1, 2).
in the present truth—the Gospel truth now present with you: formerly promised to Old Testament believers as about to be, now in the New Testament actually present with, and in, believers, so that they are "established" in it as a "present" reality. Its importance renders frequent monitions never superfluous: compare Paul's similar apology, Ro 15:14, 15.
