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.
