In these passages is the account of the nations: Moab, Ammon, and Edom, joining together to march on Judah. When King Jehoshaphat learned of it he was greatly afraid. These combined enemies would be too strong for Judah to overcome.
Jehoshaphat gathered the people together to pray to the Lord for help. They rightly focused on God for their deliverance, and God responded to Jehoshaphat through one of the Prophets. God told Jehoshaphat at that God Himself would fight against the army marching on Judah. Judah would not have to fight them.
When the armies marched on Jerusalem, God caused them to fight among themselves. The armies destroyed each other. All Judah had to do was gather the spoil.
This example demonstrates how important it is for us to put our trust in God when things seem hopeless, or when we don’t have a ready solution. The Bible says, “Trust in the Lord and lean not on your own understanding. In all ways acknowledge Him and He will make your paths straight.” I have found this passage to be so helpful. Many times in my life it helped me to avoid acting in rash or hasty ways.
I have found that when I put my trust completely in God, He will work things out in marvelous ways. My task is to trust Him. That is what He wants from me.
