Jesus sent his disciples ahead by boat while he went to a mountain to pray. A storm arose and the disciples struggled against the wind and waves. They saw Jesus walking on the water towards them and were afraid, thinking he was a ghost. Jesus reassured them not to be afraid, and invited Peter to walk on water with him. However, Peter began to sink when he took his eyes off Jesus and doubted. Jesus rescued Peter and calmed the storm. The story teaches that with faith in Jesus, we can face life's storms.
