31:4 Paul had a keen sense of the conflict which every soul must wage with the agencies of evil that are continually seeking to deceive and ensnare, and he had worked untiringly to strengthen and confirm those who were young in the faith. He had entreated them to make an entire surrender to God; for he knew that when the soul fails to make this surrender, then sin is not forsaken, the appetites and passions still strive for the mastery, and temptations confuse the conscience.
