John 6:63

Verse 63. It is the Spirit that quickeneth. These words have been understood in different ways. The word "Spirit," here, evidently does not refer to the Holy Ghost, for he adds, "The words that I speak unto you, they are spirit." He refers here, probably, to the doctrine which he had been teaching in opposition to their notions and desires. "My doctrine is spiritual; it is fitted to quicken and nourish the soul. It is from heaven. Your doctrine or your views are earthly, and may be called flesh, or fleshly, as pertaining only to the support of the body. You place a great value on the doctrine that Moses fed the body; yet that did not permanently profit, for your fathers are dead.
