John 6:57

We live by virtue of our union with the Son of God. As God-man Mediator, the Lord Jesus lives by the self-existent Father who has sent Him, and in the same manner we live by the Savior who has quickened us. He who is the source of our life is also the sustenance of it. Living is sustained by feeding. We must support the spiritual life by spiritual food, and that spiritual food is the Lord Jesus. Not His life, or death, or offices, or work, or word alone, but Himself, as including all these. On Jesus Himself we feed.

This is set forth to us in the Lord's Supper, but it is actually enjoyed by us when we meditate upon our Lord, believe in Him with appropriating faith, take Him into ourselves by love, and assimilate Him by the power of the inner life. We know what it is to feed on Jesus, but we cannot speak it or write it. Our wisest course is to practice it and to do so more and more. We are entreated to eat abundantly, and it will be to our infinite profit to do so when Jesus is our meat and our drink.

The Lord Jesus the same night in which he was betrayed took bread: and when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.

The bread that I will give is my flesh, which I will give for the life of the world.
