"And the three companies blew the trumpets, and brake the pitchers, and held the lamps in their left hands, and the trumpets in their right hands to blow withal .... And they stood every man in his place round about the camp: and all the host ran, and cried, and fled" (Judges 7:20-21).
That is the strangest battle ever fought. God had told Gideon to go down and drive out of the land the Midianites, but his army is too large; for the glory must be given to God, and not to man. And so proclamation is made that all those of the troops who are afraid and want to go home, may go; and twenty two thousand of them scampered away, leaving only ten thousand men.
But God says the army is too large yet, and so He orders these ten thousand remaining to march down to a stream, and commands Gideon to notice in what manner these men drink of the water when they come to it. If they get down on all fours and drink, then they are to be pronounced lazy and incompetent for the campaign; but if, in passing through the stream, they scoop up the water in the palm of their hands and drink, and pass on, they are to be the men selected for the battle. Well, the ten thousand men march down to the stream and most of them go down on all fours and plunge their mouths, like a horse or an ox, into the water and drink - but there are three hundred men who, instead of stooping, just dip the palm of their hands in the water and bring it to their lips, "lapping it as a dog lappeth." Those three hundred brisk, rapid, enthusiastic men are chosen for the campaign. They are each to take a trumpet in the right hand and a pitcher in the left hand, and there must be a lamp inside the pitcher, and then at a given signal they are to blow the trumpets and throw down the pitchers and hold up the lamps. So it was done.
It is night. I see a great host of Midianites, sound asleep in the valley of Jezreel. Gideon comes up with his three hundred picked men and surrounds the camp on all sides, and when everything is ready, the signal is given and they blow the trumpets and they throw down the pitchers and hold up the lamps, and the great host of Midianites, waking out of a sound sleep, take the crash of the crockery and the glare of the lamps for the coming on of an overwhelming foe; and they run and cut themselves to pieces and horribly perish.
The lessons of this subject are very spirited and impressive. This seemingly valueless lump of quartz has the pure gold in it. The smallest dew drop on the meadow at night has a star sleeping in its bosom, and the most insignificant passage of Scripture has in it a shining truth. God's mint coins no small change.
I learn in the first place from this subject, the lawfulness of Christian stratagem. You know very well that the greatest victories ever gained by Washington or Napoleon were gained through the fact that they came when and in a way they were not expected - sometimes falling back to draw out the foe, sometimes breaking out from ambush, sometimes crossing a river on rafts; all the time keeping the opposing forces in wonderment as to what would be done next. The northern troops beat their life out in the straightforward fight at Fredericksburg, but it was through strategy they got the victory at Lookout Mountain.
You all know what strategy is in military affairs. Now I think it is high time we had this art sanctified and spiritualized. In the Church, when we are about to make a Christian assault, we send word to the opposing force when we expect to come, how many troops we have, and how many rounds of shot, and whether we will come with artillery, infantry, or cavalry, and of course we are defeated. There are thousands of men who might be surprised into the Kingdom of God. We need more tact and ingenuity in Christian work. It is in spiritual affairs, as in military, that success depends in attacking that part of the castle which is not armed and entrenched.
