Luke 9:36

And when the voice was past, Jesus was found alone. And they kept it close, and told no man in those days any of those things which they had seen.

Moses and Elijah, having spoken those things for which they were sent, departed to make way for a still greater manifestation of glory. But in the interval, while they were withdrawing, Peter regained full consciousness for a moment, though he was still dazed with the wonder of what he had seen. He was filled with a peculiar ecstasy, with the joy characteristic of the great festivals of the Jews, especially of that of the Feast of Tabernacles. He was loath to see the visitors from heaven depart, and therefore proposed to build three tabernacles, one for Christ, one for Moses, and one for Elijah, that the communion thus begun might continue indefinitely, and the disciples might be witnesses of the heavenly glory for an indefinite length of time. But, as the evangelist says, Peter was not clear in his mind as to what he was really saying. The entire happening on the Mount of Transfiguration was for Christ a taste and pledge of the glorification which should be His after His final great Passion. For the disciples it was to be a strengthening of their faith in view of the days through which they would be obliged to pass, days of severest trial and tribulation. But to all that believe in Christ and share the persecutions which come upon the believers for His sake, the future transfiguration and glorification is here pictured. "This revelation shows that this life is nothing in comparison with that to come, which will surely fall to the lot of those that have died to the world in Christ. And we owe it to God to thank Him with sincere praise that He thus far humiliated Himself to reveal such glory to us, and that He wanted to make us sure of the hope of the life to come by means of such a beautiful, open, and mighty revelation."

While Peter was still speaking these words, there came a cloud, not a dark and dreary mass, but one refulgent with heavenly brightness. So obvious was this feature that the poor, sinful mortals instinctively shrank back and were filled with fear as they entered into the cloud. Here was such a cloud of glory as that which filled the Most Holy Place of the tabernacle and the Temple when the Lord wanted to speak to the children of Israel. But whereas in those days there was only the lid of the ark of the covenant that served as a type of the things to come, now the great Mercy-seat Himself was in the midst of the cloud of God's glory, surrounded with heavenly brightness. And now came the revelation of God the Father, who spoke out of the cloud as a witness for His Son: This is My Son, the Chosen One; hear Him, give obedience to Him. Hereby the prophetic dignity of the High Priest of the New Testament was raised above even that of the elect prophets of old. Beside Him even the highest, greatest, and best of mortals falls away into insignificance: Jesus must be all in all. As soon as the voice had been heard, Jesus was found alone and in His former lowly appearance, that of a servant. All traces of the heavenly glory had been removed. But the disciples had heard what they were to do. They had the Word of Jesus, the Word of the Gospel; this they should hold fast, to this they should render obedience. We Christians need not worry because the bodily presence of Christ has been removed from us; for we also have the Word and Jesus in the Word in all the glory of His wonderful love unto our salvation. In obedience to a command of Christ the three disciples kept silence concerning this wonderful revelation in those days. They did not speak of this experience until after the resurrection of Christ.
