Matthew 26:25-29: in context

At the Last Supper, as they are eating, Jesus takes bread, gives thanks, breaks it, and gives it to his disciples, saying, take, eat; this is my body. Then he takes the cup, gives thanks, and gives it to them, saying, drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. In the bread and the cup, Jesus gives his disciples himself, his body given and his blood poured out for them, for the forgiveness of sins.

In this meal Jesus gives his disciples the meaning of his coming death. The bread is his body, given for them; the cup is his blood, poured out for many for the forgiveness of sins. His death, which lay hours ahead, was not a tragedy that befell him but a sacrifice he gave, his body and blood offered for the forgiveness of sins. And he gives this to his disciples to receive: take, eat; drink of it, all of you. He offers them the benefit of his sacrifice, his body and blood given for them, and calls them to receive it. This reveals the heart of what Christ did and gives us. His blood was poured out for the forgiveness of sins; his death was a sacrifice for us, that our sins might be forgiven. Without the shedding of blood, Scripture says, there is no forgiveness; and Christ shed his blood, poured out for many, that we might be forgiven. The Supper holds this out to us: the body given and the blood shed for the forgiveness of our sins, offered for us to receive. And Jesus commanded that this meal be kept, so that his people would continually receive and remember his sacrifice. As often as you eat this bread and drink this cup, Paul says, you proclaim the Lord's death until he comes. In the Supper, we receive again the meaning of Christ's death, his body and blood given for our forgiveness, and remember and proclaim it. This is a gift to receive with gratitude and faith. Christ's body was given and his blood poured out for the forgiveness of our sins; and he holds this out to us, calling us to receive it, take and eat, drink of it. We do not earn forgiveness; it is given, purchased by the body and blood of Christ, offered to us to receive. And the Supper looks forward as well as back: Jesus said he would drink it new with them in his Father's kingdom, so that the meal is a foretaste of the feast to come. This calls us to receive with faith and gratitude the sacrifice of Christ held out to us. His body was given and his blood shed for the forgiveness of our sins; and in the Supper he holds this out to us to receive and remember. We come not to earn forgiveness but to receive the sacrifice of Christ, his body and blood given for us, with gratitude and faith, remembering his death until he comes, and looking forward to the feast in his kingdom, receiving the gift of forgiveness purchased by the body given and the blood poured out for us.

Do I receive with gratitude and faith the sacrifice of Christ held out to me, his body given and his blood poured out for the forgiveness of my sins, or do I try to earn a forgiveness that has already been purchased, and can the Supper, where Jesus gives his body and blood for the forgiveness of sins and calls his disciples to take and receive, move me to receive his sacrifice with faith, remembering his death until he comes and looking forward to the feast in his kingdom?
