Just as the artist foresees in his mind how he will make each stroke of the brush on the canvas—how short or long or wide (and there is no other way if the painting is to become a masterpiece!) where he should use red or blue—so God does the same, and a thousand times more, in our lives through much suffering and many strokes of color. He does so in order to achieve in us the masterpiece that pleases him the most, so long as we truly embrace these gifts—these bitter circumstances—from him.
— Johannes Tauler (c. 1300-1361)
