And when even was now come, His disciples went down unto the sea, and entered into a ship, and went over the sea toward Capernaum. And it was now dark, and Jesus was not come to them. And the sea arose by reason of a great wind that blew. So when they had rowed about five and twenty or thirty furlongs, they see Jesus walking on the sea, and drawing nigh unto the ship: and they were afraid. But He saith unto them,
“It is I; be not afraid.”
Then they willingly received Him into the ship: and immediately the ship was at the land whither they went. John 6:16-21
Walking on water. Only one Man ever accomplished doing that with success. There is the gospel account where Jesus bids Peter to come to Him, Peter gets out of the boat and does for a moment, but when he sees the waves, the rough sea around him, he sinks calling for the Lord to help him (Matthew 14:26-31).
So who has the authority to take control over the elements, and to command others to even do so, but God? No one.
We must recognize who Jesus Christ is. He is in fact the Anointed One, the Messiah, the Christ, the Sent One by God. He is in fact the Son of God, the Son of Man, the God-Man who is fully God and fully Man. He is Man, yet without sin. He can walk on water. He can calm the storms.
He can also heal the sick, cause the cripple to walk and leap about, open the eyes of those born blind, open the ears of the deaf, and the mouth of the mute. He still went to the cross bearing the sins of the world, dying; and He was buried taking away all our sin, shame, guilt and condemnation; and He arose and came out of that grave, and forever lives seated by the Father’s right hand.
Repent of your sins, believe Him and be saved.
