Their minds are full of darkness; they wandered far from the life God gives because they have closed their minds and hardened their hearts against him. Ephesians 4:18
Our heart becomes hardened when we choose to ignore that inner feeling inside which nudges us to do or say something. When this feeling is ignored too many times the heart becomes insensitive to conviction and it becomes hardened. It's important to realize the impact of our actions or inactions. Have you declined your compassion to others with a hard heart?
