What is true of the natural qualities of the soul is preeminently true of faith. So long as we are quietly at rest amid favorable and undisturbed surroundings, faith sleeps as an undeveloped sinew within us. But when we are pushed out from all these surroundings, with nothing but God to look to, then faith grows suddenly into a cable, a monarch oak, a master-principle of the life. As long as the bird lingers by the nest, it will not know the luxury of flight. As long as the trembling boy holds to the bank, or toes the bottom, he will not learn the ecstasy of battling with the ocean wave.
