After the death of Joäo Batista, who is practically Jesus’ predecessor in terms of being a prophet, Jesus was sad and tried to be alone to reflect what happened. As for each person the death of a relative or loved one, so for Jesus, the loss of Joäo Batista was a sad event.
The people where waiting at the beach and wanted to accompany Jesus and did not want to give up. Jesus was on the boat, the people on earth. There were so many people – Jesus was concerned about people’s food – (see John 6: 10-13) — extraordinary miracle.

Jesus wanted to be alone and ordered the disciples to get on the boat and go to another place, himself staying on earth to pray.
When the boat found itself in the middle of the sea (Sea of ​​Galilee, lake of Genesaré), a storm arose, the waves were covering the boat, Jesus was distant. At the beginning of the fourth night watch (between 3 and 6 am) Jesus walked over the water towards the boat. The disciples were frightened and afraid. Jesus in the water? …. is it a phantom ?? When we are afraid, clear  thinking  fails and the mind is disturbed, so we think, that we can see a phantasma. But ghosts are a thing of the devil, because God did not give us the spirit of fear, but the spirit of love. We shouldn’t be afraid of God, but respect Him! In the human view, the disciples were unable to understand that he was not a  phantasm , but Jesus himself. Pedro, a person, who was always the first to take the initiative, said:

see: Mateo 14: 28-31
28 “Lord,” said Peter, “if it is you, send me to meet you over the water”.
29 “Come,” he replied.
So Peter got out of the boat, walked on the water and went to Jesus. 30 But when he noticed the wind, he was afraid and, starting to sink, he shouted: “Lord, save me!”
31 Immediately Jesus reached out and took hold of him. And he said, “Man of little faith, why did you doubt?”
Jesus bet the possibility, Peter took the faith. But after the first wind, he lost his faith, he no longer looked at the target (Jesus) and he almost sank. Faith has to materialize with attitudes, we have to put faith into practice, not take our eyes off the desired target. Don’t just talk about faith !! We are experiencing a lack of faith, especially today. It is a very big difference to speak: Lord, Lord! – and put faith into practice. Those who do God’s will do not speak, but act. When we put faith into practice, miracles happen. We identified our possibility at the time of the tests, at the time of wind.
At the time of fear, at the time of the wind, Peter’s faith disappeared. Instead of keeping an eye on Jesus, he looked at the storm and started to sink. Looking at god, we get everything !!

Let’s look at Goliath and David: Goliath was very big, but David managed with faith in God, to knock him down, with the stone.  Goliath fell and so David had come close, took the enemy’s sword and cut off his head. David grew up on himself, only with faith in God.
1 Samuel 17:45 „David, however, said to the Philistine,“ You come against me with a sword, with a spear and with darts, but I am going against you in the name of the Lord of hosts, the God of Israel’s armies, whom you challenged. 46 This very day the Lord will deliver you into my hands, I will kill you and cut off your head. “

Faith must be great! Jesus for example called Paul  “a man of little faith”  when he saved him from the waters. Paul doubted, but the faith must be growing, always increasing, if not, we will have greater difficulties. Many situations, which could be ministered easier with faith, get bigger without faith and cannot be resolved.
Jesus is always close to us, when our sea (the world) is rough, our boat is close to sinking. We hear the Lord’s orders! He tells us to move on or take his hand to hold our hand.
Our faith must always be practiced, be in action, so Jesus makes possible in our lives everything that seems impossible. Have faith !!
