Through being overcome with sleep, the disciples heard little of what passed between Christ and the heavenly messengers. Failing to watch and pray, they had not received that which God desired to give them,—a knowledge of the sufferings of Christ, and the glory that should follow. They lost the blessing that might have been theirs through sharing His self-sacrifice. Slow of heart to believe were these disciples, little appreciative of the treasure with which Heaven sought to enrich them. (DA 425.1) MC VC

Yet they received great light. They were assured that all heaven knew of the sin of the Jewish nation in rejecting Christ. They were given a clearer insight into the work of the Redeemer. They saw with their eyes and heard with their ears things that were beyond the comprehension of man. They were “eyewitnesses of His majesty” (2 Peter 1:16), and they realized that Jesus was indeed the Messiah, to whom patriarchs and prophets had witnessed, and that He was recognized as such by the heavenly universe.

While they were still gazing on the scene upon the mount, “a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is My beloved Son, in whom I am well pleased; hear ye Him.” Matthew 17:5. As they beheld the cloud of glory, brighter than that which went before the tribes of Israel in the wilderness; as they heard the voice of God speak in awful majesty that caused the mountain to tremble, the disciples fell smitten to the earth. They remained prostrate, their faces hidden, till Jesus came near, and touched them, dispelling their fears with His well-known voice, “Arise, and be not afraid.” Matthew 17:7. Venturing to lift up their eyes, they saw that the heavenly glory had passed away, the forms of Moses and Elijah had disappeared. They were upon the mount, alone with Jesus. (DA 425.3) 2 I MC VC
