The Person, Posture, and Patience of Jesus.
John writes his gospel with the purpose of proving that Jesus is the Christ, the Son of God, so that we might believe, and in believing, that we might have life through His name. John places a discourse of teaching before or after each of the miracles he writes about. John 6:16-21 includes two of four miracles that occur in this account. Other details, including the other two miracles, are found in the parallel accounts in Matthew 14 and Mark 6. In both the feeding of the 5,000 and this passage of John 6:16-21, we see that God is Provider, providing food and safety to His people. Jesus is Jehovah-Jireh in the flesh (John 6:35).
