Sir: My Son, I beg you refrain from uttering such blasphemies against your heavenly Father. Were he to reward us ultimately based on our works, what soul could stand. But blessed is the man against whom the lord will not count his sin. The one who works his wages are not counted as a gift but as his due. My Son, forget your works and soley rely on his grace. No more have a detestable mind but be renewed.
Sinner: Do you mean then sir that God rewards me not because of my works but because of his grace towards me?
Sir: Yes my Son. Only Jesus has done the necessary work. You only need to accept it and repent continually. Now bow your head and pray in faith, ask for whatever you desire - Your sins are forgiven and the righteousness of Jesus Christ covers you this day and for the rest of your life.
The sinner went away rejoicing, giving glory to God for his grace and mercy and for the righteousness of Jesus Christ.
