Without faith that it is possible to render reality understandable by means of our theoretical constructs, without faith in an inner harmony of the world, there could be no science. This faith is and always will be the basic motivation behind every creative scientific idea. All our endeavors, all the dramatic conflicts between old and new ideas are supported by the eternal desire for knowledge, the unshakeable faith in cosmic harmony which becomes stronger the more difficulties loom before us.
~ from THE EVOLUTION OF PHYSICS by Albert Einstein and Leopold Infield
Having the faith to take life one piece at a time- to live it in the knowledge that there is something of God in this for me now, here, at this moment- is of the essence of happiness. It is not that God is a black box full of tests and trials and treats. It is that life is a step on the way to a God who goes the way with us. However far, however perilous.
