For the human body to be healthy, it must feed on the right diet. In like manner, the human mind and spirit must feed on the right spiritual diet to be healthy, mentally, spiritually and morally. To do so, we must feed on living food, which is the word of God in the bible. Jesus says in Matthew 4:4 that man should live "On every word that comes from the mouth of God." Jesus also says in John 6:63, "The words I have spoken to you are spirit and they are life." This implies that the human mind and spirit should live on the word of God, which is the living food and living truth that comes directly from God through His inspired writers of the bible.
Any word, idea, teaching, doctrine, concept, philosophy, and belief that is not in harmony with the word of God that is revealed in the bible, is not spirit, life, nor truth. Therefore, it is not living food. It is therefore dead food that pollutes both mind and spirit. If you feed on it, it will destroy you.
I encourage you to read, memorize, study and meditate on the word of God, so that you will be healthy in mind and spirit. When you are healthy in these ways you will be an act like God. This is our purpose here on earth. GOD BLESS YOU AS YOU DO SO
