Instead of asking yourself whether you believe or not, ask yourself whether you have this day done one single thing because he said, “Do it,” or once abstained because he said, “Do not do it.” I do not say that you will not have, as a matter of course, done this or that good thing that fell into harmony with the words of Jesus. But have you done or not done any act, as a conscious decision made because he said to do it or not?
— George MacDonald, Knowing the Heart of God, p. 30
