On the next day, the multitude that stood on the other side of the sea saw that there was no other boat there, except the one in which his disciples had embarked, and that Jesus hadn't entered with his disciples into the boat, but his disciples had gone away alone.
Jesus knew that these people wanted him to be king not because they felt any spiritual need, but because they thought he had magical powers that could supply all their daily needs. He urged them not to think just of physical and temporal blessings, but to seek the spiritual and eternal life that he offered (John 6:25-27). People cannot earn this life through doing good works; they can only accept it by faith (John 6:28-29). Jesus does not need to make food fall from heaven as in Moses’ day in order to prove his power. He himself is the true bread from heaven (John 6:30-33).
