In this lesson Keeping The Faith Without Losing Your Mind, we learn If there is ever a battle that we must fight, and a victory we must win, this is it! I don’t believe our greatest enemy is Satan. Yes, he is the adversary that is seeking to devour. But the Bible makes it plain that he is a defeated enemy. Jesus defeated him at Calvary, and in hell when he took the keys to death, hell, and the grave! He arose victorious, and gave the victory to his church. No, Satan is not our greatest problem. Our problem is ourselves.
