We don’t have exact numbers, but we know three different nations had risen up to overthrow Judah.
King Jehoshaphat didn’t call his advisors or a meeting of the cabinet, He called on the Lord. After his prayer, the Spirit of the Lord came upon Jahaziel in the congregation and he prayed.
2 Chronicles 20:15 And he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat, Thus saith the Lord unto you, Be not afraid nor dismayed by reason of this great multitude; for the battle is not yours, but God's.
If we will be honest and admit it, we can do nothing apart from the grace and help of the Lord.
The battle is too great, the storm too strong, the valley too deep.
But through Christ we are more than conquerors. When we realize we can’t overcome, that is when God will.
The battle is not yours, but God’s. Trust Him.
