Gerhard and Walther

Just as the sanctified fruit of God should exist in all our actions, so also it should exist in our praise and exaltation of God. We must remember that we are standing before the throne and praising Him before whose great majesty the holy angels tremble and humble themselves.—Johann Gerhard, Schola Pietatis III:377.

Behold, dear Christian, if you want to know how to divide and use the Gospel and the Law in your heart for salvation, you must ask God for this blessed ability. The Holy Ghost is the only teacher who can teach you correctly.—C. F. W. Walther, God Grant It!, p. 680.
