“Even on my worst days, it doesn’t change God’s immense goodness toward me.”—Keith Tucci. These are the seeds of rebellion (Psalm 106): forgetting God, losing wonder at His majesty, overlooking His abundant kindness, quickly forgetting His Word, envying others, and grumbling. A rebellious heart becomes a hard heart. It won’t hear God, won’t flow in thanksgiving, and a heart without thanksgiving does not share its faith or carries a testimony.
