Praise Him In The Battle!
As soon as they started shouting and praising, God set ambushes against the men of Ammon, Moab, and Mount Seir as they were attacking Judah, and they all ended up dead. 2Chronicles 20:22 MSG
Jehoshaphat was king and he was about to be engaged in a battle. His battle strategy was to shout and praise the Lord. As a result of praising the Lord, the enemy was killed. Can you imagine using praise as your only weapon against the enemy? The Lord fought that battle and won. He will fight for you. Let's praise him in the battle. This battle strategy worked back then and I'm sure that it will work now.
