His prayer consisted of prideful boasts of what he did and of disdain for those he despised. The tax collector, who represented those despised by religious people, humbled himself before God and begged for mercy. His prayer was heard by God because he had remorse for his sins. He sought God with humility rather than with pride. This parable presents both an opportunity and a warning.
Pride leads to illusion and self-deception.
Humility helps us to see ourselves as we really are and it inclines us to God's grace and mercy. God dwells with the humble of heart who recognize their own sinfulness and who acknowledge God's mercy and saving grace. God cannot hear us if we despise others. Lord, may your love control my thoughts and actions that I may do what is pleasing to you. Show me where I lack charity, mercy, and forgiveness toward my neighbor.
