For many years I lived without any real awareness of the impact of my thoughts upon the condition of the soul. Not realizing that my thoughts were actually the food for my soul, the substance from which it evolves its strength and health and beauty, or upon which it may become weak and unhealthy and deformed.
We feed upon whatever we are thinking. If we think low and corrupt thoughts, we bring diseases upon our body by eating corrupt and improper food (in the mind). The man who thinks about self, feeds on self just in proportion to the amount of thought he gives to self. He may at last become puffed up with self and suffer from the dreadful disease of self-conceit and self-importance.
On the other hand, if we think of Christ, we feed on Christ. We eat His flesh and blood by filling our souls with believing thoughts of Him.
The Jews asked, “How can this man give us his flesh to eat?” And a great many people ask the same today.
The answer becomes apparent to those who fill their souls with believing thoughts of Christ. They will find practically that they do feed upon Him, to the joy and delight of their hearts
Jesus confirms this when He says, “It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life."
He meant them to understand that to feed on Him was to receive and believe His words, that it was not His literal flesh they were to eat, but the words that He spake unto them, the truths that He taught them.
