Leviticus 12-15: Purity

Just how dirty was it, wandering around in the desert with thousands of others and their children and their flocks.  How were the Children of Israel to survive without water purification tablets, Clorox and antibiotics?  They had to be constantly vigilant and willing to be placed outside the camp or have their dwelling destroyed for the safety of the community.  The commands in chapters 12 to 15 may seem a little dramatic to us now, but they were absolutely essential for the survival of the Israelites.  Not only did their hearts have to be pure, but their bodies and surroundings had to be pure as well.  What's up with this God?  You, who created the heavens and earth, could have done away with mildew, boils, and infectious diseases.  Oh yeah, that's right.  One man's sin destroyed the perfect world you created.  Now, in addition to envy, greed, and lust, the Israelites have to deal with all the manifest results of uncleanliness.  All they can do is bring their sacrifices of a sin offering and burnt offering to the priest so he can make atonement for them. Only a sacrifice will wash away their sin.  Only blood will make them whole again.
