Hebrews 12:15 Bitterness. When grace rules less in our hearts peace leaves and bitterness sweeps in. The saved child of God that is always critical, angry, un-involved, etc may be bitter. Bitterness is sneaky and subtle, but destructive. The only cure is grace pouring into the bitter heart, and in turn that bitter person sharing the grace given them. In the words of the verse, “look diligently.” -PB
