But Jesus looked at them and said to them, “With men this is impossible, but with God all things are possible.” – Matthew 19:26

Nothing is impossible to the man who knows how to overcome heaven by wrestling intercession. When we have seen one, two, or ten, or twenty penitents converted, and when we have sometimes been heartily thankful that a hundred have been added to this church in a month, ought we ever to have been satisfied? Should we not have felt that the prayer, which was blessed to the conversion of a hundred, had it been more earnest, might, in the divine purpose, have been answered with the conversion of a thousand? Why not? You will say, “We have not enough ministers.” But God can make them. I tell you, sirs, He could find ministers for His truth-ay, if He willed it, among the very offscourings of the earth. He can take the worst of men, the vilest of the vile, and change their hearts, and make them preach the truth if He pleases. We are not to look to what we have. The witness of the senses only confuses those who would walk by faith. See what He did for the church in the case of Saul of Tarsus. He just went up to the devil’s army, and took out a ringleader, and said to him, “Now, sir, you preach the gospel which once you despised.” And who preached it better? Why, I should not wonder if ere long in answer to prayer we see the Ritualistic clergy preaching the gospel! Who can tell-the Romish priests may yet do it and repeat the tale of Luther and Melancthon. Were not Luther, and Melancthon, and Calvin, and their comrades, brought out of Papal darkness to show light unto the people? We have heard with our ears, why may we not see with our eyes, the mighty works of God? The Lord can find His men where we know nothing about them…Let us not despair. If we will but pray for it, our heavenly Father will deny His children nothing. Come, do but come, in simplicity of heart, and according to your faith shall it be done unto you. ~ C.H. Spurgeon
