As for the censors of these men who have sinned at the cost of their lives, let them be made into hammered plates as a covering for the altar, for they offered them before the Lord, and they became holy. Thus they shall be a sign to the people of Israel. (Numbers 16:38 ESV)
"There was a man named Korah who led a rebellion against Moses’ leadership (Numbers 16:2-3). Korah led some of the men of Israel to use censors for themselves that God had instructed Moses to use as a covering for the altar. God, to punish the rebels’ sin and rid Israel of false leadership, caused the earth to open up and swallow Korah, his household, and his rebellion. God redeemed the sinful situation into a holy one; that is what he does with us. This is a large part of what makes the Christian faith different than other world religions. In order to be justified, or have a right standing, with the gods of many religions, one must work their way into the god or goddesses approval by being good or holy. They need to pray enough, give enough, fast enough, and do enough good all with the hope of making their god’s cut. Our God doesn’t work like that. Instead of accepting the good or holy, he seeks the sinful and makes them holy (Mark 2:17), having exchanged our sin with Jesus’ perfection (2 Corinthians 5:21). That is a fundamental difference, that he takes the sinful and makes him holy, instead of expecting the sinful to clean himself up and work his way into his favor which is impossible for man (Rom. 3:10-12). We serve a wonderful God who can turn sinners into saints."
