12 For this reason I will not be negligent to remind you always of these things, though you know and are established in the present truth. 13 Yes, I think it is right, as long as I am in this tent, to stir you up by reminding you, 14 knowing that shortly I must put off my tent, just as our Lord Jesus Christ showed me. 15 Moreover I will be careful to ensure that you always have a reminder of these things after my decease.
16 For we did not follow cunningly devised fables when we made known to you the power and coming of our Lord Jesus Christ, but were eyewitnesses of His majesty. 17 For He received from God the Father honor and glory when such a voice came to Him from the Excellent Glory: "This is My beloved Son, in whom I am well pleased." 18 And we heard this voice which came from heaven when we were with Him on the holy mountain.
19 And so we have the prophetic word confirmed, [1] which you do well to heed as a light that shines in a dark place, until the day dawns and the morning star rises in your hearts; 20 knowing this first, that no prophecy of Scripture is of any private interpretation, [2] 21 for prophecy never came by the will of man, but holy men of God [3] spoke as they were moved by the Holy Spirit.

Commentary on 2 Peter 1:12-15
(Read 2 Peter 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.
Commentary on 2 Peter 1:16-21
(Read 2 Peter 1:16-21)
The gospel is no weak thing, but comes in power, Acts 26:28. God is well pleased with Christ, and with us in him. This is the Messiah who was promised, through whom all who believe in him shall be accepted and saved. The truth and reality of the gospel also are foretold by the prophets and penmenof the Old Testament, who spake and wrote under influence, and according to the direction of the Spirit of God. How firm and sure should our faith be, who have such a firm and sure word to rest upon! When the light of the Scripture is darted into the blind mind and dark understanding, by the Holy Spirit of God, it is like the day-break that advances, and diffuses itself through the whole soul, till it makes perfect day. As the Scripture is the revelation of the mind and will of God, every man ought to search it, to understand the sense and meaning. The Christian knows that book to be the word of God, in which he tastes a sweetness, and feels a power, and sees a glory, truly divine. And the prophecies already fulfilled in the person and salvation of Christ, and in the great concerns of the church and the world, form an unanswerable proof of the truth of Christianity. The Holy Ghost inspired holy men to speak and write. He so assisted and directed them in delivering what they had received from him, that they clearly expressed what they made known. So that the Scriptures are to be accounted the words of the Holy Ghost, and all the plainness and simplicity, all the power and all the propriety of the words and expressions, come from God. Mix faith with what you find in the Scriptures, and esteem and reverence the Bible as a book written by holy men, taught by the Holy Ghost.
