We keep the charge of the Lord our God

2 Chronicles 13:1-22
Abijah went out to battle, having an army of valiant men of war, 400,000 chosen men. And Jeroboam drew up his line of battle against him with 800,000 chosen mighty warriors.
We keep the charge of the Lord our God, but your have forsaken him. Behold God is with us at our head, and his priests with with their battle trumpets to sound the call to battle against you. O son of Israel, do not fight against the Lord.
Jeroboam had sent an ambush around to come upon them from behind. When the men of Judah raised the battle shout, God defeated Jeroboam and all Israel fled before Judah, and God gave them into their hand.
Jeroboam did not recover his power in the days of Abijah.
Why?
Abijah rely on the Lord and he keep the charge of the Lord, so God helped them defeated Jeroboam, even Israel had double chosen men than Judah, but the victory is not depend on the men but on the Lord Almighty.
Priests blew the trumpets mean attack the enemy, and the men of Judah cried to the Lord, it is asked for the help from the Lord.
How?
Judah prevailed because of the Lord, so as we conquered the trouble because of the Lord. Keep the charge of the Lord our God.
