Believing in Jesus does not only mean a verbal profession of faith. In the Gospel of John, the term believing is, most often, used to describe faith that shows itself in action. This is why believing is akin to work. Jesus does not provide merely physical nourishment, but also nourishment of the mind, heart, and spirit. To know and believe in Jesus is to be sated in every aspect of life. It is to never lack or want anything, because all things are provided in him.
