28 About eight days after saying this, he climbed the mountain to pray, taking Peter, John, and James along. 29 While he was in prayer, the appearance of his face changed and his clothes became blinding white. 30 At once two men were there talking with him. They turned out to be Moses and Elijah - 31 and what a glorious appearance they made! They talked over his exodus, the one Jesus was about to complete in Jerusalem. 32 Meanwhile, Peter and those with him were slumped over in sleep. When they came to, rubbing their eyes, they saw Jesus in his glory and the two men standing with him. 33 When Moses and Elijah had left, Peter said to Jesus, "Master, this is a great moment! Let's build three memorials: one for you, one for Moses, and one for Elijah." He blurted this out without thinking. 34 While he was babbling on like this, a light-radiant cloud enveloped them. As they found themselves buried in the cloud, they became deeply aware of God. 35 Then there was a voice out of the cloud: "This is my Son, the Chosen! Listen to him." 36 When the sound of the voice died away, they saw Jesus there alone. They were speechless. And they continued speechless, said not one thing to anyone during those days 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.
