Gerhard and Walther

He who does good praises God much more than he who praises God’s goodness with his mouth.—Gerhard, Schola Pietatis, p. 36.

The fountains of divine mercy, however, flow continually and even the basest ingratitude and the most wanton misuse cannot stop them. This is a bottomless sea of love, and it can never be exhausted.... It is not as if each person has a certain amount of mercy allotted to him and God subtracts a bit of that mercy each day until the account is emptied. Each day, God treats it as if He were extending mercy for the first time. He seeks us, and shows Himself to us as a God who earnestly desires our salvation. —C. F. W. Walther, God Grant It, p. 35, 36.
