You and I have must have read several times, heard it preached on and probably studied commentaries on the entire 6th chapter of St John's Gospel: the whole discourse about the Institution of the Holy Eucharist. Jesus is True God and True Man. Being Our God made visible, He knows we should not stop at having a relationship with Him, but an INTIMACY with Him. In our human parlance, every relationship should end in an intimacy that involves the body - the whole body. This is what Catechists and Pastors should teach while preparing couples for the Sacrament of Matrimony; we don't leave them in the dark, guessing about their mutual rights and responsibilities to live and mature together as members of the Mystical Body of Christ. Husband and wife give themselves totally and completely to each other in their relationship in such an intimate way that one is really willing to die for the other. This is the Holy Will of God from all eternity - not for the "pleasure" but for the will of the Creator, an act that is open to NEW LIFE and in fulfillment of the Divine plan of procreation and populating of the City of God.
So, Christ following His eternal design of the Human Person He created from the beginning, before He suffered as He ever knew all that would happen in its time, gave us HIS BODY AND BLOOD to fulfil His Holy Will to remain with us till the end of Time. As it is known, St John's Gospel got the Mind and Will of Jesus Christ in the Institution of the Holy Eucharist and its narrative. If you and I truly love Jesus Christ, we should likewise love His Will and Intent that we feed on His Body and Blood so to have life in us and be candidates for Heaven. Let us revisit the entire chapter 6 of St John's Gospel.
