Peter wanted to put Moses, Elijah, and Jesus on the same plane.
The Law-Giver and the Law-Restorer, however, do not compare with the one the Law-Writer, and the Law-Fulfiller, Jesus!
God the Father responded to this unthinking suggestion from Peter:
"While he yet spake, behold, 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)
Not the Law, not the Prophets, but the Man and the Glory Jesus Christ -- We are called to hear Him!
And what was the first thing that Jesus said after His transfiguration?
"Arise, and be not afraid." (Matthew 17:7)
This point is really touching, because the very "arise" is literally "be risen."
Jesus brought them up!
While so many of us want to do something for Jesus, like Peter who wanted to build tabernacles, the truth is that Jesus wants to serve us.
In fact, He came to tabernacle over us!
"And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father, ) full of grace and truth." (John 1:14)
"Dwelt among us" is literally "tabernacled among us."
Jesus is our covering, and He wants to dwell with us.
For those who believe on Him, He also dwells within us!
"Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me." (John 15:4)
" For we are the temple of the living God. As God has said: "I will live with them and walk among them, and I will be their God, and they will be my people." (2 Corinthians 6:16)
Jesus is our tabernacle. Let Him cover you. Let Him protect you!
