Not Arrogance, but Relationship
When the psalmist says, "I am godly," he isn't claiming sinless perfection. Commentators explain the Hebrew word used, 'chasid,' means a 'favored one' or 'devoted one.' The plea is based on a covenant relationship with God, like a child appealing to a parent for help. It's a declaration of belonging to God, not a boast of personal merit.
