Martin Luther, in one of his conflicts with the Devil, was asked by the arch-enemy if he felt his sins forgiven?
"No," said the great Reformer, "I don't feel that they are forgiven, but I know they are because God says so in His Word."
Paul did not say, "Believe on the Lord Jesus Christ, and thou shalt feel saved," but "Believe on the Lord Jesus Christ, and thou shalt be saved." Acts 16:31.
No one can feel that his sins are forgiven. Ask that man whose debt was paid by another: "Do you feel that you debt is paid?" "No", is the answer, "I don't feel that it is paid; I know from this receipt that it is paid. And I feel happy because I know that it is paid." So with you.
