Jesus then reminded them that it was not Moses that gave them that bread in the desert, but that God alone gives the true bread from heaven. Said He, “The bread of God is He which cometh down from heaven, and giveth life unto the world.” Still failing to see what Jesus meant, they asked that they might evermore have that bread of life, when He told them plainly that He Himself was the living bread, saying, “I am the bread of life; he that cometh to Me shall never hunger, and he that believeth on Me shall never thirst.” EVCO 235.2
Still later Jesus said, “Verily, verily, I say unto you, He that believeth on Me hath everlasting life. I am that bread of life. Your fathers did eat manna in the wilderness, and are dead. This is the bread which cometh down from heaven, that a man may eat thereof, and not die. I am the living bread which came down from heaven; if any man eat of this bread, he shall live for ever; and the bread that I will give is My flesh, which I will give for the life of the world.” 1John 6:32-51. EVCO 236.1
Just as the people ate that bread which came from the Lord Jesus, and were strengthened by it, even so they might, if they had believed, have received spiritual life from Him. His life is righteousness, and all who eat of Him in faith must receive righteousness. Like ancient Israel, they were eating bread from heaven, and like them they did not appreciate it, so as to receive the full benefit of it. EVCO 236.2
