3. Bitterness. Paul told the Ephesians, “Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you” (Eph. 4:32). Yet many Christians today have never let go of their resentments. They don’t realize that people who seethe with anger over past hurts poison themselves—and make it impossible to develop close friends. Bitterness will make you unfriendly—and people will avoid you because you are toxic. We must learn to pay close attention to our hearts and purge any grudge the instant it takes root in our souls.
