Christ speaks in this way for a good reason: He wants to teach us by His supper that as bread and wine sustain us in this temporal life, so His crucified body and shed blood are true food and drink for our souls to eternal life.¹ But, even more important, He wants to assure us by this visible sign and pledge, first, that through the working of the Holy Spirit we share in His true body and blood as surely as we receive with our mouth these holy signs in remembrance of Him,² and, second, that all His suffering and obedience are as certainly ours as if we personally had suffered and paid for our sins.³
