Abijah and his men suddenly detected their desperate position, and did the only wise thing. When, with a shock of surprise, they saw that 'behold! the battle was before and behind them,' they 'cried unto the Lord, and the priests sounded with the trumpets.' The sharp, short cry from thousands of agitated men ringed round by foes, and the blare of the trumpets were both prayers, and heartened the suppliants for their whirlwind charge, before which the men of Israel, double in number as they were, broke and fled. The defeat was thorough, and, for a while, Rehoboam and his kingdom were 'brought under,' and a comparatively long peace followed. Our text gathers up the lesson taught, not to Judah or Israel alone, by victory and defeat, when it declares that to rely upon the Lord is to prevail. It opens for us the secret of victory, in that old far-off struggle and in to-day's conflicts. I. We note the faith of the fighters. 'They relied,' says the chronicler, 'upon the Lord.' Now the word rendered 'relied' is one of several picturesque words by which the Old Testament, which we are sometimes told, with a great flourish of learning, has no mention of 'faith,' expresses 'trust,' by metaphors drawn from bodily actions which symbolise the spiritual act. The word here literally signifies to lean on, as a feeble hand might on a staff, or a tremulous arm on a strong one. And does not that picture carry with it much insight into what the essence of Old Testament 'trust' or New Testament 'faith' is? If we think of faith as leaning, we shall not fall into that starved misconception of it which takes it to be nothing more than intellectual assent. We shall see there is a far fuller pulse of feeling than that beating in it. A man who leans on some support, does so because he knows that his own strength is insufficient for his need. The consciousness of weakness is the beginning of faith. He who has never despaired of himself has scarcely trusted in God. Abijah's enemies were two to one of his own men. No wonder that they cried unto the Lord, and felt a stound of despair shake their courage. And who of us can face life with its heavy duties, its thick-clustering dangers and temptations, its certain struggles, its possible failures, and not feel the cold touch of dread gripping our hearts, though strong and brave? Surely he has had little experience, or has learned little wisdom from the experience he has had, who has yet to discover his own weakness. But the consciousness of weakness is by itself debilitating, and but increases the weakness of which it is painfully aware. There is no surer way to sap what strength we have than to tell ourselves what poor creatures we are. The purpose and end of self-contemplation which becomes aware of our own feebleness is to lead us to the contemplation of God, our immortal strength. Abijah's assurance that 'God is with us at our head' rang out triumphantly. Faith has an upper and an under side: the under side
