Wanting the Whole Person (Micah 6:1-8)

The Lord offers Israel a series of options regarding sacrifices that might relieve them of the coming exile.  You would think that Israel, with a sacrificial system, could offer the Lord enough sacrifices to turn away the foreign army.  You can almost imagine the people thinking about going to the temple, pooling resources, and making the priests work overtime to gather together enough to avoid impending doom.  This is possible until the Lord asks them about child sacrifice.  Does the Lord really want them to sacrifice their children?  If there is not enough then what can appease this Holy God?  How can we please such a sovereign, mighty, and holy God as mere fallen creatures?
