From "The Problem of Pain" by C.S. Lewis

You asked for a loving God: you have one. The great spirit you so lightly invoked, the "Lord of terrible aspect," is present: not a senile benevolence that drowsily wishes you to be happy in your own way, not the cold philanthropy of a conscientious magistrate, nor the care of a host who feels responsible for the comfort of his guests, but the consuming fire Himself, the Love that made the worlds, persistent as the artist's love for his work and despotic as a man's love for a dog, provident and venerable as a father's love for a child, jealous, inexorable, exacting as love between the sexes.
