It didn't take long before crowds were following Jesus everywhere He went. He gave the Sermon on the Mount (in Galilee) to a large number of people. They brought their sick, their demon-possessed, and those who were hungry to hear the Word of the Lord, and by this time, He was physically exhausted. Needing some "down time," he slipped into a boat along with his disciples and promptly fell into a deep sleep.
Without warning, a furious storm came up on the lake, so that the waves swept over the boat. But Jesus was sleeping. The disciples went and woke him, saying, "Lord, save us! We're going to drown!" He replied, "You of little faith, why are you so afraid?" Then he got up and rebuked the winds and the waves, and it was completely calm. The men were amazed and asked, "What kind of man is this? Even the winds and the waves obey him!" ~~Matthew 8:24-27
Just after this, Jesus called Matthew the Tax Collector to follow Him, endured criticism for dining with "tax collectors and sinners" (Matthew 9:11), answered detailed questions from the masses about the Law and grace, healed more of the sick, raised a young girl from the dead, preached continuously, heard that His mother, sisters and brothers were concerned and wanted to speak to Him, began to teach in parables, learned that John the Baptist had been beheaded at the whim of the step-daughter of Herod Antipas, and fed five thousand men (not including women and children) with five loaves and two fish (and still had leftovers).
Once again, exhausted, He needed some down time.
Immediately Jesus made the disciples get into the boat and go on ahead of him to the other side, while he dismissed the crowd. After he had dismissed them, he went up on a mountainside by himself to pray. When evening came, he was there alone, but the boat was already a considerable distance from land, buffeted by the waves because the wind was against it.
During the fourth watch of the night Jesus went out to them, walking on the lake. When the disciples saw him walking on the lake, they were terrified. "It's a ghost," they said, and cried out in fear. But Jesus immediately said to them: "Take courage! It is I. Don't be afraid." "Lord, if it's you," Peter replied, "tell me to come to you on the water." "Come," he said. Then Peter got down out of the boat, walked on the water and came toward Jesus. But when he saw the wind, he was afraid and, beginning to sink, cried out, "Lord, save me!" Immediately Jesus reached out his hand and caught him. "You of little faith," he said, "why did you doubt?" And when they climbed into the boat, the wind died down. Then those who were in the boat worshiped him, saying, "Truly you are the Son of God." ~~Matthew 14:22-33
