Manna from Heaven

John 6:30-33 
30 Therefore they said to Him, “What sign will You perform then, that we may see it and believe You? What work will You do? 31 Our fathers ate the manna in the desert; as it is written, ‘He gave them bread from heaven to eat.’ ” 32 Then Jesus said to them, “Most assuredly, I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven. 33 For the bread of God is He who comes down from heaven and gives life to the world.”

God gave Israel manna as bread down from heaven for forty years; it was not Moses, but God, and now here He does again coming down to allow us to partake of God Himself with life giving bread. Jesus Christ is who we eat of, not a teacher or leader or prophet.  Only God gives life, and we find our nourishment in fellowship and union with Him.
