In John 6:53-58 our Lord says,
Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.54 Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day.55 For My flesh is food indeed, and My blood is drink indeed.56 He who eats My flesh and drinks My blood abides in Me, and I in him.57 As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me.58 This is the bread which came down from heaven — not as your fathers ate the manna, and are dead. He who eats this bread will live forever.”
In a moment I will read the words of institution and I will invite you to take up a morsel of bread into your mouth. And then I will invite you to take up a cup of wine to your lips. I can say with all authority that when you receive this bread, you will be eating the body of Christ. And when you receive this wine, you will be drinking the blood of Christ. This is so not because of a crude superstition or because a miracle has taken place. This is so by the Word of God. What God tells you in His Word is true, so when you partake of bread and wine together as the body of Christ in faith, with the Spirit of God present with you, you are actually partaking of Christ. He is sharing His life with you and strengthening you for your fight with sin. He is sharing His invincible life with you, the same life He laid down as He crumpled under the wrath of God on the cross and the same life He took up as He arose triumphant from the grave. This is the same life that He declared is the life of the world in John chapter 6. This is the same life which Revelation 22 figures as a tree whose leaves are for the healing of the nations.
Christ crucified and eaten by sinners. Christ pierced and drunk by a people who were far off but who have been brought near. Look on Him and rejoice, people of God. Your Savior is drawing you upward to give you life in His body, through union with Him by faith.
Come, let us taste and see that the Lord is good.
