Theory is not faith, nor anything like it. Faith is obedience; theory, I know not what. Trust in God. Obey the word – every word of the Master. That is faith; and so believing, your opinion will grow out of your true life, and be worthy of it.
— George MacDonald, Unspoken Sermons, Third Series, “Justice,” quoted in Discovering the Character of God, compiled by Michael R. Phillips, p. 268.
