Self-Righteousness leads to spiritual blindness because it overlooks personal accountability. Pride, self-centeredness, envy, jealousy, and lack of empathy is just a few characteristics that someone operating in self-righteousness possess. Appearing to be perfect, when everyone has flaws is the reality of not taking personal accountability. We all are a work in progress, and no one should think more highly of themselves than someone else as to put others down. Instead, we should be willing to see that we all are God's children that are standing in need of His grace and mercy daily.
