Why pray?

Thomas Merton once wrote:

Without courage we can never attain to true simplicity. Cowardice keeps us "double minded" - hesitating between the world and God. In this hesitation, there is no true faith - faith remains an opinion. We are never certain, because we never quite give in to the authority of an invisible God. This hesitation is the death of hope. We never let go of those visible supports which, we well know, must one day surely fail us. And this hesitation makes true prayer impossible - it never quite dares to ask for anything, or if it asks, it is so uncertain of being heard that in the very act of asking it surreptitiously seeks by human prudence to construct a makeshift answer. 

What is the use of praying if at the very moment of prayer, we have so little confidence in God that we are busy planning our own kind of answer to our prayer?

That pretty much sums it up for me...Faith, I believe is a verb. Something to be practiced. I don't know that I will ever get it perfect. I'm not sure what my life would be without it...
