"We may have flattered ourselves, as did Nicodemus, that our life has been upright, that our moral character is correct, and think that we need not humble the heart before God, like the common sinner: but when the light from Christ shines into our souls, we shall see how impure we are; we shall discern the selfishness of motive, the enmity against God, that has defiled every act of life. Then we shall know that our own righteousness is indeed as filthy rags, and that the blood of Christ alone can cleanse us from the defilement of sin, and renew our hearts in His own likeness."
