And 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. Mark 9:2 ESV

When Jesus took His three closest friends up a mountain, He began to show them who He really was in a way they had never seen before. Yet in spite of the beauty and holiness of that moment, Jesus did not tarry on the mountain. No! He came down the mountain to heal one young boy. And He left the highest mountain of all, that place in Heaven when He came down to the manger, He came for you and me. But before His mission was finished, He had one more mountain to climb, the mountain that had a cross waiting at the top where He suffered and died for our sins. He paid the terrible price so that one day when this life is over, if we have put our faith in Him, we will be able to join Him forever on that mountain in Heaven!

Though he was God, he did not think of equality with God as something to cling to. Instead, he gave up his divine privileges he took the humble position of a slave and was born as a human being. When he appeared in human form.
Philippians 2:6-7 NLT
