John 6:35 - Matthew Poole's English Annotations on the Holy Bible

I am the bread of life; the bread that giveth spiritual and eternal life, and the bread that upholdeth and maintains spiritual life; the Messiah, whom God hath sent into the world, to quicken those that are dead in trespasses and sins, Ephesians 2:1; and to give eternal life to as many as the Father hath given me. But those that have this life, must come unto me; which he interprets in the next phrase by believing in him. Thus he taketh them off all gross and carnal conceptions of eating and drinking in a carnal manner; and minds them to think of getting and maintaining another kind of life than they dreamed of. By believing in him, we have formerly showed is to be understood a receiving of him as the Mediator and Saviour of men, and closing with him, and committing their souls in all their spiritual concerns unto him; and he that doth so (saith he) shall never hunger nor thirst; that is, shall never want any thing necessary for him for life and eternal happiness. And for things of this life, he shall have food convenient for him; he shall be fed, Psalms 37:3. See such a promise, Isaiah 49:10.
