"My life is but a weaving, betwixt the Lord and me, I do not choose the color --He worketh steadily. He weaveth sorrow and I in foolish pride, Forget He sees the upper, and I the underside. Not tilll the loom is silent, and the shuttle cease to fly, shall God unroll the canvas and explain the reason why. The dark threads are as needful in the Weaver's skillful hand as the threads of gold and silver in the pattern He has planned." 

(Grant Colfox Tullar)
