28 Now about eight days after these sayings he took with him Peter and John and James, and went up on the mountain to pray. 29 And as he was praying, the appearance of his countenance was altered, and his raiment became dazzling white. 30 And behold, two men talked with him, Moses and Eli'jah, 31 who appeared in glory and spoke of his departure, which he was to accomplish at Jerusalem. 32 Now Peter and those who were with him were heavy with sleep, and when they wakened they saw his glory and the two men who stood with him. 33 And as the men were parting from him, Peter said to Jesus, "Master, it is well that we are here; let us make three booths, one for you and one for Moses and one for Eli'jah" --not knowing what he said. 34 As he said this, a cloud came and overshadowed them; and they were afraid as they entered the cloud. 35 And a voice came out of the cloud, saying, "This is my Son, my Chosen; listen to him!" 36 And when the voice had spoken, Jesus was found alone. And they kept silence and told no one in those days anything of what 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.
