18 It happened, as he was praying alone, that the disciples were with him, and he asked them, “Who do the multitudes say that I am?” 19 They answered, “‘John the Baptizer,’ but others say, ‘Elijah,’ and others, that one of the old prophets is risen again.” 20 He said to them, “But who do you say that I am?”
Peter answered, “The Christ of God.”
21 But he warned them, and commanded them to tell this to no one, 22 saying, “The Son of Man must suffer many things, and be rejected by the elders, chief priests, and scribes, and be killed, and the third day be raised up.” 23 He said to all, “If anyone desires to come after me, let him deny himself, take up his cross, [1] and follow me. 24 For whoever desires to save his life will lose it, but whoever will lose his life for my sake, the same will save it. 25 For what does it profit a man if he gains the whole world, and loses or forfeits his own self? 26 For whoever will be ashamed of me and of my words, of him will the Son of Man be ashamed, when he comes in his glory, and the glory of the Father, and of the holy angels. 27 But I tell you the truth: There are some of those who stand here, who will in no way taste of death, until they see the Kingdom of God.”
28 It happened about eight days after these sayings, that he took with him Peter, John, and James, and went up onto the mountain to pray. 29 As he was praying, the appearance of his face was altered, and his clothing became white and dazzling. 30 Behold, two men were talking with him, who were Moses and Elijah, 31 who appeared in glory, and spoke of his departure, [2] which he was about to accomplish at Jerusalem. 32 Now Peter and those who were with him were heavy with sleep, but when they were fully awake, they saw his glory, and the two men who stood with him. 33 It happened, as they were parting from him, that Peter said to Jesus, “Master, it is good for us to be here. Let’s make three tents: one for you, and one for Moses, and one for Elijah,” not knowing what he said. 34 While he said these things, a cloud came and overshadowed them, and they were afraid as they entered into the cloud. 35 A voice came out of the cloud, saying, “This is my beloved Son. Listen to him!” 36 When the voice came, Jesus was found alone. They were silent, and told no one in those days any of the things which they had seen.

Commentary on Luke 9:18-27
(Read Luke 9:18-27)
It is an unspeakable comfort that our Lord Jesus is God's Anointed; this signifies that he was both appointed to be the Messiah, and qualified for it. Jesus discourses concerning his own sufferings and death. And so far must his disciples be from thinking how to prevent his sufferings, that they must prepare for their own. We often meet with crosses in the way of duty; and though we must not pull them upon our own heads, yet, when they are laid for us, we must take them up, and carry them after Christ. It is well or ill with us, according as it is well or ill with our souls. The body cannot be happy, if the soul be miserable in the other world; but the soul may be happy, though the body is greatly afflicted and oppressed in this world. We must never be ashamed of Christ and his gospel.
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.
