Look again, and see Joshua as he goes up to the walls of Jericho. If you had asked what they had with which to bring down the walls of that city, all you would have seen would have been a few rams' horns. They must have looked very mean and contemptible in the eyes of the men of Jericho. Perhaps the city contained some men who were giants; as they looked over the walls and saw the Israelites marching around the city blowing these horns, they must have appeared very insignificant. But God can use the base things, the despised things. However contemptible an instrument a ram's horn may have appeared in the sight of man, the people went on blowing them as they were commanded; and at the appointed time down came the walls, and the city was taken. The Israelites had no battering rams; no great armor or mighty weapons of any kind. They simply took what they had, and God used it to do the work. Look at Samson going out to meet a thousand Philistines. What has he with him? Only the jawbone of an ass! If God could use that, surely He can use us, can he not? Do you tell me He cannot use this woman, that little boy? There is not one whom He cannot use, if we are willing to be used. I remember hearing a Scotchman say, when I was in Great Britain ten years ago, that there was probably not a man in all Saul's army but believed that God _could_ use him to go out and slay the giant of Gath. But there was only one solitary man who believed that God _would_ use him. David went out to meet Goliath and we know the result. We all believe that God _can_ use us; we want to take a step further and believe that He _will_ use us. If we are willing to be used, He is willing to use us in His service. How contemptible these smooth stones that David took out of the brook would have appeared to Goliath! Even Saul wanted David to take his armor, and put it on. He was on the point of yielding; but he took his sling and the five smooth stones and went out. The giant of Gath fell before him. Let us go forth in the name of the God of hosts, using what we have, and He will give us the victory. When I was in Glasgow a few years ago, a friend was telling me about an open-air preacher who died there some years before. This man was preaching one Sabbath morning on Shamgar. He said: "I can imagine that when he was ploughing in the field a man came running over the hill all out of breath, and shouted: 'Shamgar! Shamgar! There are six hundred Philistines coming toward you.' Shamgar quietly said: 'You pass on; I can take care of them, they are four hundred short.' So he took an ox goad and slew the whole of them. He routed them hip and high. And the Israelites had again fulfilled before their eyes the words: 'One shall chase a thousand and two shall put ten thousand to flight.'" Now-a-days it takes about a thousand to chase one, because we do not realize that we are weak in ourselves and that our strength is in God.
