Gerhard and Walther

Grant me Your grace that I from henceforth daily sing praise to You and thank You for all Your benefits with my mouth and heart. Grant that I praise You at all times for Your great grace and glorify and offer praise to You. (Tobit 8:18).—Johann Gerhard, Schola Pietatis III:384

True Christians, are those in whom Jesus, makes a beginning of such love, but they never bring it to perfection. It is, therefore, evil delusion when a person thinks he is able to justify himself before God and make himself holy by the fulfillment of the commandment to love the neighbor.—C. F. W. Walther, God Grant It!, p. 689.
