Speechless

 Now Peter and those who were with him were heavy with sleep, but when they became fully awake they saw his glory and the two men who stood with him. And as the men were parting from him, Peter said to Jesus, “Master, it is good that we are here. Let us make three tents, one for you and one for Moses and one for Elijah”—not knowing what he said. As he was saying these things, a cloud came and overshadowed them, and they were afraid as they entered the cloud. And a voice came out of the cloud, saying, “This is my Son, my Chosen One; listen to him!” And when the voice had spoken, Jesus was found alone. And they kept silent and told no one in those days anything of what they had seen. (Luke 9:32-36 ESV)
During their times with Jesus, they had heard Him teach so many truths over and over again. Often, they would mumble in the background about what He said. Sometimes, they (especially Peter) would erupt with some bold statemet - be it correct or not.  Having just proclaimed that Jesus is the Christ, he does not realize the depth of His statement, until He sees it: Christ alone is to be revered and followed. This leaves even Peter speechless.  May we be in such awe of Christ today as we worship Him.
