Q75. How does the Lord's Supper remind you and assure you that you share in Christ's one sacrifice on the cross and in all his gifts?

In this way: Christ has commanded me and all believers to eat this broken bread and to drink this cup. With this command he gave this promise:1 First, as surely as I see with my eyes the bread of the Lord broken for me and the cup given to me, so surely his body was offered and broken for me and his blood poured out for me on the cross. Second, as surely as I receive from the hand of him who serves, and taste with my mouth the bread and cup of the Lord, given me as sure signs of Christ's body and blood, so surely he nourishes and refreshes my soul for eternal life with his crucified body and poured-out blood.
