Prideful obedience to God’s law is no obedience at all. It is like a respectful thief or a honest liar. It is for the praise of men and self-righteousness before God. It cares little about God and only about it’s self. It’s fear is of man rather than God. It stand’s in self-praise to tell God how it’s much goodness outweighs it’s little evil. Realizing the truth that our righteousness is of no value to Him, leaves us standing in horror with nothing but dirty rags in our hands before that frightful and awesome Judge. He value’s humility before obedience for true humility leads to obedience. Humble obedience is not to justify but rather to give thanks and reverence to our Creator, who justified us not by our obedience but by His own.
