Self-righteousness is the belief that the self can produce righteousness. The fact is that every person who is following Jesus Christ is led and taught by the Holy Spirit moment by moment. When we listen and acknowledge Him, He imparts His faith, a Divinely inspired certainty that what He said is true. This certainty gives us access into His grace. His grace does the righteousness through us. True righteousness is a gift of God–it is God doing His works through us. Every other form of righteousness, whether Christian or non-Christian, is filth. It is self-righteousness.
