28 Now it came to pass, about eight days after these sayings, that He took Peter, John, and James and went up on the mountain to pray. 29 As He prayed, the appearance of His face was altered, and His robe became white and glistening. 30 And behold, two men talked with Him, who were Moses and Elijah, 31 who appeared in glory and spoke of His decease which He was about to accomplish at Jerusalem. 32 But Peter and those with him were heavy with sleep; and when they were fully awake, they saw His glory and the two men who stood with Him. 33 Then it happened, as they were parting from Him, that Peter said to Jesus, "Master, it is good for us to be here; and let us make three tabernacles: one for You, one for Moses, and one for Elijah"--not knowing what he said. 34 While he was saying this, a cloud came and overshadowed them; and they were fearful as they entered the cloud. 35 And a voice came out of the cloud, saying, "This is My beloved Son. Hear Him!" 36 When the voice had ceased, Jesus was found alone. But they kept quiet, and told no one in those days any of the things they had seen.

Commentary on Luke 9:28-36
(Read Luke 9:28-36)
Christ's transfiguration was a specimen of that glory in which he will come to judge the world; and was an encouragement to his disciples to suffer for him. Prayer is a transfiguring, transforming duty, which makes the face to shine. Our Lord Jesus, even in his transfiguration, was willing to speak concerning his death and sufferings. In our greatest glories on earth, let us remember that in this world we have no continuing city. What need we have to pray to God for quickening grace, to make us lively! Yet that the disciples might be witnesses of this sign from heaven, after awhile they became awake, so that they were able to give a full account of what passed. But those know not what they say, that talk of making tabernacles on earth for glorified saints in heaven.
