|Matthew Henry's Concise Commentary|
6:47-51 The advantage of the manna was small, it only referred to this life; but the living Bread is so excellent, that the man who feedeth on it shall never die. This bread is Christ's human nature, which he took to present to the Father, as a sacrifice for the sins of the world; to purchase all things pertaining to life and godliness, for sinners of every nation, who repent and believe in him.
Verse 48 repeats once more the statement of vers. 32, 35 (see notes): I am the Bread of life. Not only do I give you more than Moses gave your fathers, but I am the Father's Gift. I myself am the Gift - I am the Bread of which, if you partake, you will hunger no more, you will need no more, you will die no more: the life then thrilling through you will be eternal. "The invisible God is the Source of eternal life; the human nature of the Son of God is the visible form which contains and imparts this to the souls of men" (Archdeacon Watkins).
