Purified by Reverse Osmosis

I was reading on my bottled water today... (and yes, I do drink bottled water... and yes, I do realize I am killing the oceans or something like that... but I have recently started recycling the bottles... so I think I get a couple of green points)... anyway... all that to say: it said "purified by reverse osmosis". Of course, being the very curious person that I am, I had to set out to find out what reverse osmosis meant. Well, as all of you no doubt remember from your definitions in your science classes: osmosis is the filtration of water through a semi-permeable membrane from highest concentration to lowest (and I'm just kidding, I know you all didn't remember that! hehe). In reverse osmosis however, there is an external application of pressure which actually makes the water go from a higher concentration to a lower concentration through the semi-permeable membrane. I thought this was interesting, because sometimes I think that God uses the hard things as pressure in our lives pressing us towards purity.
Funny how God would apply the exact right amount of pressure in our lives to drive us against the natural bent towards becoming more impure. When we are born we are already in sin, but the longer we go through life the worse it gets. We learn new ways to sin and violate God's laws. In some ways we are going through that semi-permeable membrane called life and getting our lives filled with a higher and higher concentration of bad habits, ugly character traits, bitterness from experiences, and generally getting yuckier with the passing days. Then when Christ enters our lives, He turns everything around. The flow goes backwards. And not by anything that we can do on our own. It only the divine power that He brings that is able to apply the needed pressure to reverse the whole flow. Death and sin start working backwards (as Aslan says). Instead of getting more filled with filth, we start being purified by the washing of the water of the Word, and God begins His sanctification (or just general cleaning out) of our lives. The purity that we so desperately need starts to slowly take action in our lives. A beautiful, beautiful work. I think its also very interesting that sometimes the purity of peoples lives seem to be directly in proportion to the amount of suffering (pressure anyone?) that they go through. God has a very special process it seems by which when we go through really hard times He really delights in making us more beautiful.
