Jesus was not impressed or seduced by a crowd that wanted to make him king (John 6:15). This crowd was willing to support Jesus as long as he gave them what they wanted – bread.
But Jesus wants to accomplish the will of the heavenly Father and not that of the people.
Some love Jesus for what he gives us. But he wants us to love him for who he is: the Son of Man (6:27) from heaven (6:29), with eternal life (6:27).
