II Chronicles 20:20-25
The weapon of praise is a mighty weapon that God has given to us in fighting the enemy. This is not necessarily how we would choose to fight the enemy, nor does it seem as though it would work in opposing such a hostile army in the Word of God but God chose praise to defeat the enemy nonetheless. The enemy’s army we battle against daily in our hearts and minds can be overpowered by the expressed admiration and praise directed to our God.
Jehovah God used the weapon of praise to defeat the children of Moab and the children of Ammon. Jehoshaphat, King of Judah, rose up early and went to the wilderness with his army and spoke these words to them, “Believe in the Lord your God, and ye shall be established, believe his prophets, so shall ye prosper” (II Chronicles 20:20b). To be established means to be supported by God. Why wouldn’t we want to believe in Him if He is going to support us against the enemy?
After Jehoshaphat had directed them to fast and pray (vs. 3,4) he spoke to his people and appointed singers to sing praises unto the Lord of His beauty and holiness as they marched out before the enemy. “And when they began to sing and to praise, the LORD set ambushments against the children of Ammon, Moab and mount Seir, which were come against Judah; and they were smitten” (II Chronicles 20:22). God often makes wicked people destroy one another and that is exactly what they did. As the army of Judah came forward to see what had happened, there was a multitude of dead bodies fallen to the earth and none escaped. The weapon of praise was in action.
Why do you think this simple weapon could work against the mighty armies of Moab, Ammon and Mount Seir? Only by God can the enemy be defeated through the power of praise. We need only to obey and praise our great God to have victory over Satan. We may not be able to see our enemy fallen to the ground as the Children of God did, but the enemy will be defeated in our hearts and minds through the weapon of praise.
Note: the song the Children of God sang just before they were to go into battle against Moab, Ammon, and Mount Seir was Psalm 136, it contains nothing but praise to our God, the Lord of lords, and Great Creator, “...for his mercy endureth forever.” Psalm 136:5b
