Where there is no sanctification of life, there is no real faith in Christ. True faith works by love. It constrains a man to live unto the Lord from a deep sense of gratitude for redemption. It makes him feel that he can never do too much for Him that died for him. Being much forgiven, he loves much. He whom the blood cleanses, walks in the light. He who has real lively hope in Christ, purifies himself even as He is pure… The faith which has not a sanctifying influence on the character is no better than the faith of devils.
