"Anything that deprives a man of real life is an enemy to that man. If real life is relationship, the dwelling on friendly and affectionate terms with God and man, then anything that separates us from God, from our better selves, and from our fellows, is an enemy. Another name for this enemy is sin. It is sin that wrecks the characters of men and deprives them of their spiritual heritage. Sin is the most subtle, treacherous, and deadly of all foes. It is the destroyer of real life."
