A love for righteousness forces a decision between radical religious fanaticism, or humble grace-based gratitude. It is helpful to consider the perspective of the speaker. On the one hand, it could be a holy God revealing His posture towards the activity of the wicked. On the other hand it could be the posture of a man who is setting his priorities and actions towards holy living. In either perspective the bar is stupidly high and impossible to get over. Accepting the reality of our depth of sinful fallenness is the beginning to be able to receive the righteousnesss of the only man who ever lived in complete integrity.
