The crowd that had just been fed by the miracle of loaves & fishes finally found Jesus and they were ready for more entertainment & food. But instead Jesus had challenged their carnal thinking & told them, “Don’t work for food that spoils, but for food that endures to eternal life.” … quoting from Isaiah 55:2 which says, “Why do you spend your money for that which is not bread, & your labor for that which does not satisfy?” But they only latched on to the word “work” and asked Him, “How consistent must we be then in working to keep God’s commandments, and what is the bare minimum work we must do?” In other words, looking at it from a totally legalistic & temporal viewpoint. But then Jesus totally blew them out of the water with His reply as He clarified what God truly required of them.. “The work of God is this: to believe in the One He has sent.”
