And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart, And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light.
Jesus took Peter, James and John into an high mountain apart for the express purpose of allowing them to see His transfiguration. To be transfigured means to change into another form or to transform.
Now there certainly was nothing wrong with Jesus that He needed to be changed into another form or transfigured. He was transfigured in front of Peter, James and John for their benefit and not for the benefit of Jesus.
Immediately after Jesus was transfigured in front of Peter, James and John, there appeared beside Jesus, Moses and Elijah and they talked with Jesus. At this point Peter got the revelation that they needed to build three tabernacles. One each for Jesus, Moses and Elijah. It was then that a bright cloud overshadowed Peter, James and John and forced their faces to the ground. A voice spake to the three saying, “This is my beloved Son, in whom I am well pleased; hear ye him.” Jesus then came and touched the three and said arise and be not afraid. When Peter, James and John lifted their eyes, the Bible says they saw no man save Jesus only.
Peter, James and John were not taken up into the mountain because they were spiritual giants worthy of a promotion but rather because they needed a new vision of Jesus that would cause them to take their eyes off people and be able to see Jesus only.
Jesus please show me your glory today so that I see no man but Jesus only!
