"You and Aaron are to number by their divisions all the men in Israel twenty years old or more who are able to serve in the army." Numbers 1:3
God wasn't looking for volunteers. He expected that every able-bodied man would serve in Israel's army. Every family was counted except for the descendants of Levi, for they were to serve the Lord through care of the Tent of the Testimony. The Levites were given no choice; God had selected them. In truth, none could choose for their own.
Sometimes, I think there is too much emphasis placed on our free-will choice. Yes, following Christ is a choice. But God doesn't merely enlist volunteers to fight the good fight; He expects service from all His children. If we are counted among His followers, service is a requirement - not an option.
Lord, help me to see how You are calling me into battle. It isn't my choice - it is Your expectation. Your children are called to impact the world in the midst of this war with our enemy. I know you aren't asking for volunteers... but count me in!
