A man doesn’t go looking for Jesus because he saw him perform a miracle. He goes looking for Jesus because he satisfies. He fills a need inside the man. Jesus is the bread. He himself—not a sign from him—is the life the man needs. And, so, like His Father, Jesus gives himself.
A man will go over hill and through valley, across lakes and streams, searching for someone, not because he saw a wonderful thing he did, but because he partook of him and his wondrous doings. He partook of him and it satisfied. He was loved. He will go because of love.
Do not work for the life you can merely see. But rather for the one you can partake—unto life; given by life.
