Then Jehoshaphat feared, and set himself [determinedly, as his vital need] to seek the Lord; he proclaimed a fast in all Judah. And Judah gathered together to ask help from the Lord; even out of all the cities of Judah they came to seek the Lord [yearning for Him with all their desire]…Did not You, O our God, drive out the inhabitants of this land before Your people Israel and give it forever to the descendants of Abraham Your friend?…O our God, will You not exercise judgment upon them? For we have no might to stand against this great company that is coming against us. We do not know what to do, but our eyes are upon You. – 2 Chronicles 20:3-4,7,12
By the time Jehoshaphat became the king, Judah was a small nation, and the surrounding nations could easily defeat them. We learn that the king brought in many reforms. The Bible records that and then says, After this, the Moabites, the Ammonites, and with them the Meunites came against Jehoshaphat to battle (20:1).
The most “sensible” thing would have been for the king to surrender and to forge some kind of treaty. There was no human way that such a small nation could defeat such large armies. In that context, we read that the king was afraid and why wouldn’t he be? But he didn’t stop with fear.
I want to make this point clear. To feel fear isn’t sin or failure or disobedience. In fact, we do well to think of fear as a warning to us. It’s a shout of danger. But then we must decide what to do with the fear. We can act; we can cringe; we can ignore it. King Jehoshaphat did the right thing: He set himself [determinedly, as his vital need] to seek the Lord (v. 3). He didn’t have answers, and he certainly wasn’t stupid enough to think that his tiny army could defeat his enemies. And that’s an important lesson for us to learn in our battles against Satan. Our enemy is powerful, and if we think we can defeat him by ourselves, we’re foolish and badly mistaken.
