In the Lord's discourse on spiritual nourishment, we hear Him says: "Do not labor for the food which perishes, but for the food which endures to everlasting life." (John 6:27). He then continued by talking about the true bread from Heaven the bread of God, and the bread of life. (John 6:32-35). Here He appeals to the soul for its nourishment and our thoughts to the spiritual way so as not to occupy our minds with the body and its needs.
