Have you ever been in a situation in which many of God's people are united against you? Our new church in Mexico, and another small church, just concluded a successful week of Vacation Bible School. Catholic opposition to us appears to have collapsed, while Christian opposition to us is growing.
2 Ch 20:1-2 It happened after this that the people of Moab with the people of Ammon, and others with them besides the Ammonites, came to battle against Jehoshaphat. Then some came and told Jehoshaphat, saying, "A great multitude is coming against you from beyond the sea, from Syria..."
The Moabites, Ammonites, and Seirites were brethren of the Jews, and now they had united against a Godly man. Jehoshaphat wasn't perfect, but he had yielded himself to God, was being blessed by God, and now he had himself a large group of enemies.
2 Ch 20:3 And Jehoshaphat feared, and set himself to seek the LORD, and proclaimed a fast throughout all Judah.
Jehoshaphat was afraid for a good reason: he was hopelessly outnumbered. But he set out to seek the Lord, perhaps remembering the promise that "If you seek Him, He will be found by you" (2 Chron. 15:2)
Gathering the people together, Jehoshaphat prayed, and was promised 2 Ch 20:17 You will not need to fight in this battle. Position yourselves, stand still and see the salvation of the LORD, who is with you...
Heading towards their enemies, Jehoshaphat called on the people to trust the Lord and His Word. Then they advanced, singing and praising God.
2 Chron 20:23 For the people of Ammon and Moab stood up against the inhabitants of Mount Seir to utterly kill and destroy them. And when they had made an end of the inhabitants of Seir, they helped to destroy one another.
Do the people of God want to unite against you? Leave them alone, and they can unite against each other. You don't need to fight God's people; you need to serve the Lord.
