The idea is that it is not only belief but faith which is necessary. Belief is a thing, but faith is a living being. The warners and teachers of humanity and the great preachers who have come from time to time when darkness prevailed, what message did they bring? Did they bring new religions or new theories to the world? No. Jesus Christ said, "I have not brought a new law, but I have come to fulfill the law." Who else at any time could bring a new theory? The scientist perhaps, but not the spiritual messenger. Then what did the spiritual message bring? It brought to the world a living God, a light hidden beyond words. With the spiritual message God has sent His life and light upon the world.
