When the Holy Spirit dwells in you, you will begin to notice the things that once you loved, supported, accepted or dismissed, will now come across as filthy, vile, ungodly, useless or starkly wrong. It is a supernatural work of discernment and sanctification.
"Let me have you beware of an experience which has a faith in it that was never attended with repentance. I am afraid of dry-eyed faith. That faith seems to me to be the faith of God's elect, whose eyes are full of tears. If thou hast never felt thyself a sinner, never trembled under the Law of God, never felt that thou hast deserved to be cast into Hell, I am afraid thy faith is a mere presumption, and not the faith that looks to Christ."
