Proverbs 12:20 (NKJV) — 20 Deceit is in the heart of those who devise evil, But counselors of peace have joy.
The condition of the heart. Deceit is a destructive force that resides in the heart of the person who imagines or devises evil. In time, it will destroy that person. But joy resides in the heart of the wise – those who counsel peace rather than devising evil – and joy is a life-giving force.
