A mistress is not necessarily the soft touch of a woman’s body. The mistress in a man’s relationship with God is the world, its values, and its practices. When God sees a man loving the priorities and practices of a godless world while purporting to love Him, He sees an adulterous affair and a trampling of the love He has given to the relationship.
It’s a temptation that’s tough to resist. Our world constantly invites us to go with our feelings over our faith. The world exalts image over substance, comfort over character, indulgences over ethics. It confuses net worth with self worth. It values things over people. All of these whacked out priorities pollute our relationship with God and with people. “Religion that God our Father accepts as pure and faultless is this…to keep oneself from being polluted by the world,” says James 1:27.
