2. Petrus 1:12

Wherefore--as these graces are so necessary to your abundant entrance into Christ's kingdom (Pe2 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," Pe2 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 (Pe2 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, Rom 15:14-15.

I. The importance and advantage of progress and perseverance in grace and holiness made the apostle to be very diligent in doing the work of a minister of Christ, that he might thereby excite and assist them to be diligent in the duty of Christians. If ministers be negligent in their work, it can hardly be expected that the people will be diligent in theirs; therefore Peter will not be negligent (that is, at no time or place, in no part of his work, to no part of his charge), but will be exemplarily and universally diligent, and that in the work of a remembrancer. This is the office of the best ministers, even the apostles themselves; they are the Lord's remembrancers (Isa 62:6); they are especially bound to make mention of the promises, and put God in mind of his engagements to do good to his people; and they are the people's remembrancers, making mention of God's precepts, and putting them in mind of the doctrines and duties of Christianity, that they may remember God's commandments, to do them. And this the apostle does, though some persons might think it needless, inasmuch as they already knew those thing that he writes about, and were established in the very truth that he insists upon. Observe, 1. We need to be put in mind of what we already know to prevent our forgetting it, and to improve our knowledge, and reduce all to practice. 2. We must be established in the belief of the truth, that we may not be shaken by every wind of doctrine, and especially in that which is the present truth, the truth more peculiarly necessary for us to know in our day, that which belongs to our peace, and which is more especially opposed in our time. The great doctrines of the gospel, that Jesus is the Christ, that Jesus Christ came into the world to save sinners, that those who belie…

1:12-15 Peter was writing at the end of his life, and 2 Peter is similar to works that belong to a popular Jewish genre called the testament, in which an old and respected leader gives final instructions to his children or others on his deathbed (cp. Deut 31–33; Josh 24). This genre is especially well known from a Jewish work called The Testaments of the Twelve Patriarchs.
