The Lord’s Supper
Each of the four cups was linked to one line of Exod 6:6–7a. This one tied in with God’s promise, “I will redeem you,” in v. 6c and hence specifically to his original liberation of the Israelites from p 391 Egypt
That God “will remember their sins no more” means that no action against sin will need to be taken under the new covenant. In short, based on the single sacrifice of the new covenant, all of its members experience the full and complete forgiveness of all sins.
God the Son comes into his world to fight and overcome his and his people’s enemies: Satan, the demons, sin, the grave, death, hell, and the world understood as an organized system of evil opposed to God (1 John 2:15). How does he win this mighty victory? Through his victorious life, death, resurrection, exaltation to heaven, and return.
Jesus gives this meal to his disciples.
