Who hath believed our report? and to whom is the arm of the LORD revealed? – Isaiah 53:1

Luther said he could face his enemies, but could not go up his pulpit stairs without his knees knocking together. Preaching is not child’s play; it is not a thing to be done without labor and anxiety; it is solemn work; it is awful work if you view it in its relation to eternity. Ah! How God’s minister prays for you! If you might have listened under the eaves of his chamber window, you would have heard him groaning every Sunday night over his sermons because he had not spoken with more effect; you would have heard him pleading with God, “Who hath believed our report? To whom is the arm of the Lord revealed?” Ah, when he observes you from his rest in heaven-when he sees you praying, how will he clap his hands and say, “Behold the child Thou hast given me! Behold, he prays.” I am sure when we see one brought to know the Lord, we feel very much like one who has saved a fellow-creature from being drowned. There is a poor man in the flood; he is going down, he is sinking, he must be drowned; but I spring in, grasp him firmly, lift him on the shore, and lay him on the ground; the physician comes; he looks at him, he puts his hand upon him, and says, “I am afraid he is dead.” We apply all the means in our power, we do what we can to restore life. I feel that I have been that man’s deliverer, and oh, how I stoop down and put my ear beside his mouth! At last I say, “He breathes! He breathes!” What pleasure there is in that thought! He breathes; there is life still. So when we find a man praying, we shout-he breathes; he is not dead, he is alive; for while a man prays he is not dead in trespasses and sins, but is brought to life, is quickened by the power of the Spirit. “Behold, he prayeth.” This was joyful news in heaven, as well as being noticed by God.~ C.H.
