We all have need to feed the spirit, as well as the body. Studying the Gospel, and Inviting the Spirit of the Lord into our hearts, minds and homes is the only sure way we can stay focused on our eternal goals, and not be deceived. "For how knoweth a man the master whom he has not served, and who is a stranger unto him, and is far from the thoughts and intents of his heart?" (Mosiah 5:13)
