Moses interceded for the children of Israel when they were worshipping that glitzy cow. He could of said "Yep, God your right they are idolatrous and carnal...strike em dead Lord, burn em up", and ya know that would of made Moses life soooo much easier. Moses risked his life to ask mercy on behalf of a bunch of partying worldly rebels. God listened, and then Moses was stuck with having to lead the knuckleheads.
God loved Moses for his heart to love others. Moses was a type of Jesus, he saw others problems and said Im going to reconcile that problem, even if it means I have to die to do so.
We should have the same heart, one that says...these people are wrong, but God put me here to love them, help them and reconcile them.
2 Cor 5:16 So from now on we regard no one from a worldly point of view.
