Why is being an empty vessel important for salvation?

In the analogy of the widow and her pot of oil, the empty vessels represent people who recognize their spiritual poverty and need for God. This posture of emptiness is crucial because God does not fill vessels that are already full of self-righteousness or pride. Only those who know they are empty—void of any goodness or merit—can be filled with God's grace and salvation through Christ. Therefore, acknowledging our emptiness allows us to truly receive the abundant grace that God offers freely to all who believe.
