Thoughts on Germ X

So my wife, Carla, is a nurse.   And therefore, she is acutely aware of germs and what they do and stuff.  So we have Germ X everywhere...various places in the house, in the car, at the office, etc.  And the bottle says right there on the bottom...kills 99.99% of germs.

However, from Carla's microbiology class a few years ago, apparently it isn't just the Germ X, or even the soap in handwashing, that does the trick.  Apparently, it's the rubbing.  No matter how you "sanitize" your hands, you must rub them together vigorously, for that is what really sheds the germs!

It kinda reminds me of 1 Peter 1:6-7, where we are told that the "rubbing" makes us stronger...healthier...more faithful...
