The battle is not yours, but God's

Returning to 2 Chronicles, chapter 20 finds Judah being attacked by several of its neighbors. King Jehoshaphat assembles the people, and, rather than trying to concoct some scheme himself, he instead appeals to God's protection. In verse 9 (KJV), he prays, 

If, when evil cometh upon us, as the sword, judgment, or pestilence, or famine, we stand before this house, and in thy presence, (for thy name is in this house,) and cry unto thee in our affliction, then thou wilt hear and help.

God's answer (verses 15-17, KJV) reads,

Be not afraid nor dismayed by reason of this great multitude; for the battle is not yours, but God's. To morrow go ye down against them ... Ye shall not need to fight in this battle: set yourselves, stand ye still, and see the salvation of the Lord with you ... for the Lord will be with you.

When we're confronted with trouble, it's so easy to rest on our own schemes, or find our own solutions. Instead, Jehoshaphat turns directly to God, not with clever words or deep philosophy, but rather with faith. (Note Jehoshaphat's confident wording: though wilt hear and help.) Let us learn from Jehoshaphat's example!
