Mark 9:2–9
At the Transfiguration, Jesus conversed with two Old Testament pillars—Moses and Elijah. A voice from heaven proclaimed, “This is my Son, whom I love. Listen to him!” and immediately Jesus was left standing alone in front of Peter, James, and John. This pivotal moment displayed Christ as the hope of the world as He would provide a New Covenant through His death and resurrection, bringing light and life to this dark world.

2And after six days Jesus took with him Peter and James and John, and led them up a high mountain by themselves. And he was transfigured before them, 3and his clothes became radiant, intensely white, as no one on earth could bleach them. 4And there appeared to them Elijah with Moses, and they were talking with Jesus. 5And Peter said to Jesus, “Rabbi, it is good that we are here. Let us make three tents, one for you and one for Moses and one for Elijah.” 6For he did not know what to say, for they were terrified. 7And a cloud overshadowed them, and a voice came out of the cloud, “This is my beloved Son; listen to him.” 8And suddenly, looking around, they no longer saw anyone with them but Jesus only.
9And as they were coming down the mountain, he charged them to tell no one what they had seen, until the Son of Man had risen from the dead.
