Out of a loving desire for us to reach our eternal destination, he gives us his flesh and blood as food and drink for the journey. The destination is not just any land but the Kingdom of God. Nothing in this world can sustain us in the journey; only the living flesh and blood of God himself. Thus, only the Eucharist can bring us to our salvation. To deprive ourselves of the Eucharist is to make it impossible for us to reach the new Promised Land - Heaven.
