Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap. - Galatians 6:7, NKJV
Satan never mentions the consequences of sin. He never mentions the psychological trauma that follows an abortion. He never mentions the dirty feeling of being used after sleeping with your date that haunts your marriage relationship years later. He never mentions the panic and fear that grip you every time you answer the phone after cheating on your tax return. There are serious consequences to sin. Always. Without exception. Adam ate the forbidden fruit his wife had offered, “Then the eyes of both of them were opened, and they realized they were naked” (Gen. 3:7, NIV).
Satan had told Eve her eyes would be opened and she would be like God, knowing good and evil. In one sense he had been right. Eve’s eyes were opened, but in a grotesque way. She knew good, but also that she was separated from it. She knew evil because now she was saturated in it. She knew good and evil in a way God never intended her to know — through her own experience. And she was deeply ashamed.
