Why is it important for Christians to understand their unworthiness?

It is essential for Christians to grasp their unworthiness because it cultivates humility and gratitude. As illustrated by Mephibosheth's response to David — acknowledging himself as 'a dead dog' — this recognition is critical in understanding our position before a holy God. When we realize that we are inherently sinful and undeserving of God's grace, we come to value the salvation offered through Christ even more. This awareness leads to a deeper appreciation of God's mercy, allowing us to respond with love, worship, and obedience, fulfilling our duty as His followers.
