Grace remits sin and peace quiets the conscience. Sin and conscience torment us, but Christ has overcome these fiends now and forever. Only Christians possess this victorious knowledge given from above. These two terms, grace and peace, constitute Christianity. Grace involves the remission of sins, peace and a happy conscience. Sin is not canceled by lawful living, for no person is able to live up to the law…the fact is the more a person seeks credit for himself by his own efforts, the deeper he goes into debt. Nothing can take away sin except the grace of God. In actual living, however it is not so easy to persuade oneself that by grace alone, in opposition to every other means, we obtain the forgiveness of our sins and peace with God.

Martin Luther
