John 6:52

His flesh to eat; they meant literally. And the true answer to that question was, he would not in any way give them literally his flesh to eat. That was not his meaning. But by eating his flesh, he meant, believing on him as a Saviour, and thus receiving spiritual life and nourishment from him. Men often make objections to what they call the doctrines of Christ, when in fact their objections are not against his doctrines, rightly understood, but only against their own misconceptions of them; and the putting of a literal meaning upon such of his words as were designed to be figurative, and convey only a spiritual meaning, is absurd. John 7:34-36.
