Being by his faith replaced afresh in paradise and created anew, he (the believer)does not need works for his justification, but that he may not be idle, but that he may exercise his own body and preserve it. His works are to be done freely, with the sole object of pleasing God.
Martin LutherFor that purpose Christ instituted holy baptism, thereby to clothe you with his righteousness. It is tantamount to his saying, My righteousness shall be your righteousness; my innocence, your innocence. Your sins indeed are great, but by baptism I bestow on you my righteousness; I strip death from you and clothe you with my life.
Martin Luther
