When they are banished (as John) into remote places, or shut up (as Paul and Silas) in close places, he will find access to them, and will be nigh them. He will not leave them comfortless when they seem to be tossed with tempests and not comforted. (2.) The concern Christ has for his disciples in distress: He drew nigh to the ship for therefore he walked upon the water, as he rides upon the heavens, for the help of his people, Deu. 33:26. It is natural for heavy bodies to sink in water, but Christ walked upon the water as upon dry land, which was more than Moses’s dividing the water and walking through the water. The power Christ has over the laws and customs of nature, to control and dispense with them at his pleasure.
"When they had rowed about three or four miles, they saw Jesus approaching the boat, walking on the water and they were frightened." ~ John 6:19 Bible Commentary about Jesus Walking on Water ( John 6) The disciples immediately begin to worship Jesus and recognize that he truly is the Son of God. They climb back into the boat and the storm stops. Jesus reaches his hand down and grabs Peter. As soon as Peter gets scared of the wind and waves and takes his eyes off Jesus he beings to sink. Peter climbs out of the boat and begins to walk on the water to Jesus.
Jesus invites Peter to come to walk on the water with him. Peter then questions Jesus saying if it really is Jesus, to call Peter to come to walk on the water to him. Jesus calls to them saying "Take courage! It is I. Jesus comes walking to them on the water and the disciples become scared thinking Jesus is a ghost. During the journey a dangerous storm overtakes the boat the disciples are in and they begin to wonder where God was. Jesus asked the apostles: ‘Where is your faith?’ They said to one another: “Even the wind and the sea obey him.” The apostles learned that if they trusted Jesus completely, they did not need to be afraid of anything.The miracle of Jesus feeding the 5,000 had just finished and Jesus wanted some time alone to pray so he told his disciples to get on a boat and go to the other side of the Sea of Galilee. The apostles woke Jesus up, shouting: ‘Teacher, we are about to die! Help us!’ Jesus got up and said to the sea: “Be quiet!” Right away, the wind and the sea became calm. Waves crashed into the boat, and the boat filled with water. While he was asleep, a violent storm came up. At another time, when Jesus and the apostles sailed to the other side of the sea, Jesus went to sleep in the back of the boat. This was not the only time that Jesus controlled the weather.
Can you imagine how the apostles felt? They said: “You really are God’s Son.” Jesus and Peter climbed into the boat, and immediately, the storm stopped. Peter shouted: ‘Lord, save me!’ Jesus caught his hand, saying: ‘Why did you begin to doubt? Where is your faith?’ But as he got near him, Peter looked at the storm and became afraid. Peter said: ‘Lord, if it’s really you, command me to come to you.’ Jesus told Peter: ‘Come to me.’ So in the middle of the storm, Peter got out of the boat and walked on the water toward Jesus.
