Overwhelmed, Abram fell flat on his face. Genesis 17:3 (TM)

There is something about being on your knees – or in this case, on your face – before God. Not in the public "Hey look at me, aren’t I spiritual?" sense that Jesus warned against, but a very private act of humility before Almighty God. We’ve lost touch with some of those acts of humility in our proud, modern age.
