And Peter answered him, “Lord, if it is you, command me to come to you on the water.” He said, “Come.” So Peter got out of the boat and walked on the water and came to Jesus.
When Jesus asks Peter to come out and walk on the water as He was, the seas were high and the waves were crashing. When Peter began to sink, Jesus calls him on his faith. Peter had faith in Christ, it was his faith in himself that was waning. As we step out into stormy seas, we need to have faith in ourselves as much as we need to know Christ is there to give us strength.
