Gerhard and Walther

I have sinned, O Lord, and my sins are many and great beyond measure; and yet may I never voluntarily commit that most heinous sin of charging Thee with a lie, when Thou dost declare by words and by works and by an oath, that perfect satisfaction hath been rendered for mine iniquities.—Johann Gerhard, Sacred Meditation V

True, living faith is active through love. Therefore, as there is warmth and light in the presence of fire, there are love and good works in the person whose heart has been warmed by the sun of faith.—C. F. W. Walther, God Grant It!, p. 748.
