Matthew 17:5. “While he yet spake, behold, a bright cloud overshadowed them: and behold, a voice out of the cloud, which said, This is my belove Son, in Whom I am well pleased: hear ye Him.”
While Peter was absorbed with thinking about building a tabernacle for Jesus so He would stay away from Jerusalem, the Father in heaven shook His head and thought, “Peter is going to be one of the greatest men of God who ever lived; right now, though he’s just not getting it. I’d better give him something to think about!”
Remeber, Peter has just told Jesus, “Thou art the Christ, the Son of the living God!” And then he rebuked Jesus and tried to persuade Him not to go to Jerusalem. Now, he’s saying, “You are God, but I want You to stay here! I’ll even build You a tabernacle where we can worship You!”
Let’s not be too hard on Peter, though. I am of the opinion that we, who have the fullness of the Word of God, truly don’t know Who He is right now today. If we did, we’d be different than we are.
