Justin Martyr:
[Addressed to Jews:] “If they repent, all who wish for it can obtain mercy from God. The Scripture foretells that they shall be blessed, saying, ‘Blessed is the man to whom the Lord does not impute sin.’ That is, after repenting of his sins, such a man can receive remission of those sins from God. It is not as you deceive yourselves and some others who resemble you in this. For you say that even though they are sinners, the Lord will not impute sin to them, for they know God.”
