Gerhard and Walther

Anyone who trusts God is certain and sure that through God’s protection and guarding he shall endure every danger. To this end he adopts a fearless mindset and is unafraid.—Johann Gerhard, Schola Pietatis III:128,9.

No work can blot out our sin and no love can reconcile us with God. Only faith in Christ makes us just and holy before God.—C. F. W. Walther, God Grant It!, p. 495.
