V. 14, 15. _For I know that I must soon lay off my tabernacle, even as the Lord Christ hath showed me. But I will take care that ye by all means, after my departure, may keep such things in your remembrance._ Here Peter testifies of himself that he has become assured of eternal life, and to him God had shown beforehand when he should die; but this took place for our and our faith's sake, for there must have been some such persons as knew assuredly that they were elected, who should lay down and settle faith, that we might know that they preached not the doctrine of men, but the word of God. But ere they have come to such an assurance, God has thoroughly proved them first, and purified them. Thus Peter now says, I will not only remind you with the living voice, but set such things also in writing, and charge you, through others, that ye ever hold them in remembrance, through my life and after my death, and not let them go. There see how great anxiety the Apostle had for souls; yet, alas! it has helped nothing. V. 16-18. _For we have not followed cunningly devised fables, when we have made known unto you the power and coming of our Lord Jesus Christ, for we have been witnesses of His majesty, when He received from God the Father honor and praise, by a voice which came to Him from the excellent glory, this is my well-beloved Son, in whom I am well pleased; and this voice, which came from heaven, we heard, when we were with Him on the holy mount._ There St. Peter touches upon the history written in the Gospel, Matt. xvii., how Jesus took to Himself three of his disciples, Peter, James and John, and led them aside up a high mountain, and was glorified before them, and His face shone like the sun, and His clothing was white as the light, and there appeared to Him Moses and Elias, who spoke with Him, while a light cloud overshadowed them, and a voice out of the cloud said, This is my beloved Son, in whom I am well pleased; hear ye Him. When the disciples heard that, they fell on their faces, and were very much afraid. But Jesus went to them, roused them up, and said, stand up, be not afraid; then they lifted up their eyes, and saw no one but Jesus only, and when they went down from the mountain He charged them that they should tell no one of this sight till He arose from the dead.
