47 Truly I say to you, He who has faith in me has eternal life. 48 I am the bread of life. 49 Your fathers took the manna in the waste land—and they are dead. 50 The bread which comes from heaven is such bread that a man may take it for food and never see death.
Matthew Henry's Commentary on John 6:47-50
Commentary on John 6:47-51
(Read John 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.
