For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed. But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God.
Have you ever did anything in the dark? What I mean by that is try to obfuscate your actions? You were operating without the light of Christ when you did that. You probably felt sad or had a pit in your stomach. Not a good feeling! That was the Holy Spirit telling you that what you were doing was wrong and not in accordance with God's Word.
Listen to the Holy Spirit. He will guide you into all truth and righteousness!
But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God.
