We have two types of righteousness, and there are God righteousness and there is also unrighteousness of man, those who are ignorant to God righteousness and wont to establish their own righteousness and not submitted them self unto the righteousness of God, and in the book of (Isaiah.64vs6) says we are all as an unclean things and all our righteousness are as filthy rags and we all do fade as a leaf, and our iniquities like the wind have taken us away.
