Numbers 31
Midianites were responsible for enticing Israel into Baal worship. God commanded Israel to destroy them (25:16-18). When we discover sin in our lives, we must deal with it completely. Never let any traces of sin live in you…When the Israelites later entered the promise land, it was their indifferent attitude to sin that eventually ruined them. Sin will subtly destroy us. Moses dealt with sin promptly and completely. When God points out sin, response immediately with action to remove it from your life.
V48-50: After carefully accounting for all their men, the officers discovered that not one soldier had been lost in battle. At once they thanked God. After going through tough times, we should be quick to thank God for delivering us and protecting us from severe loss.
Numbers 32
The land on the east side of Jordan had been conquered. The hard work was done by all the tribes together-unity counts. But the tribes of Reuben and Gad and the half tribe of Manasseh did not stop after their land was cleared. They promised to keep working with the others until everyone’s land was conquered-perseverance and overcomer spirit. After others have helped you, do you make excuses to escape helping them? Finish the whole job, even those parts that may not benefit you directly.
