Christ is the divine Lawgiver who changed the words of the rites of arrangement of the Passover, and decided with his authority that the bread in the Lord’s Supper is a representation of his body, and the wine is a sign and token of the new covenant made with us. It commemorates the purchase of the covenant by his blood. As these two elements in the Lord’s Supper enter our stomachs producing to us strength and life, so Jesus himself is willing to dwell in us with his spiritual essence, and reside abiding in us forever. The aim of the Lord’s Supper is not to eat the bread and drink the wine, but that the believers may be dwelt with the Holy Spirit who is the Spirit of Jesus and the Lord himself. Taking the Lord’s Supper will be of no use to you if you do not accept Jesus in your heart asking him to stay forever. He says in confirmation to you: "This bread is my body. Believe in me that I may abide in you indeed."
Jesus also testified that the new covenant with God in his blood begins from the moment of this first Supper, and continues forever, in spite of the unworthiness of all men to covenant with God. In fact we all deserve immediate destruction. But the rights of the blood of Jesus Christ protect us, and produce life in us that we may receive justification, enter into holiness, and become worthy for the covenant with the holy God. This privilege is based only on grace. It is not based on our works, prayer, and fasting. Christ automatically comes to you, purifies you, and joins you together with God in a holy union. Do you believe this? God himself makes in Christ’s blood a covenant with you and with all the followers of his Son Christ. Then God will be with you. The Almighty will dwell in you! This is true and certain.
