Living on bread alone, by living in this world without Christ is actually death. Death in the Biblical sense is separation from God (Rom.6:23, Isaiah 59:1-2, Ephesians 2:1). Every person is like this by nature. We are not born into the world as God’s children, we have to be adopted as such through rebirth. Christ, opposing Satan in Matthew 4:4, quotes Deuteronomy 8:3, saying that man can ONLY live by God’s word. This was said in the context of God supplying manna to the Israelites, which manna Christ said represented him (John 6:33). So Christ is heavenly bread. We must eat him! A man only becomes a child of God and truly alive by being born again (John 3:3, 6:53-58) by hearing, understanding, believing and obeying the gospel (I Peter 1:23), which is eating and assimilating Christ. We must hear the word of Christ to live spiritually (John 5:24-25). By hearing it preached in a true church, by reading it in a faithful translation, and by the working of God’s Spirit we are resurrected from being spiritually dead and become really alive. We eat the heavenly bread. Christ comes to dwell in us. We are graciously given eternal life by God’s grace. This eternal life is friendship and true knowledge of God (John 17:3). This is what real Christians celebrate in the Lord’s Supper. Are you really living or still dead in your un-forgiven sins?
