Dr. R.C. Sproul says that the Lord’s Supper helps us realize just how important Jesus understands His death to be in the grand narrative of God’s redemption. He paraphrases Jesus’ words to His disciples: “My disciples, I know that in these past three years you have seen and heard many things, much of which you will forget. But whatever you do, do not forget my death!” As you partake of the Lord’s Supper, consciously recall His great sacrifice on our behalf.
