The question, Who shall be the first to go up and fight for us against the enemy?
is finally answered in Christ, the Lion of the tribe of Judah. He went to the cross and conquered the enemy, sin and death.1 He took upon himself our sin and judgment (a judgment much worse than getting his toes or thumbs cut of like Adoni-Bezek); he bore our shame, and rose from the dead, so that we could have his righteousness. That’s the greatest blessing we can ask for and receive. Sin may still be very familiar to us, and in large measure. It brings guilt, disgrace, shame, and pain; it wrecks a lot of things. But Christ has overcome, Christ is for us, Christ is with us, to lead us into battle, and into victory.
1 After the death of Joshua, the people of Israel inquired of the LORD, “Who shall go up first for us against the Canaanites, to fight against them?”
