Gerhard and Walther

God at times tests us for noble reasons with His response. That’s why we must wait on Him. If the desire of the heart of the petitioner is sincere, it will not immediately become lax if God does not immediately respond. Instead, it thereby will increase all the more.—Johann Gerhard, Schola Pietatis II:126.

Jesus’ testimony about Himself was divinely and irrefutably attested to by the glorious miracles He performed. As great as those signs and wonders were, however; God provided a much more glorious and shining proof in the resurrection of His only-begotten Son, a proof that was not offered even to the greatest Old Testament ambassadors and prophets of God.—C. F. W. Walther, God Grant It!, p. 350.
