Much of the power of Christianity today is the natural result of organized forces. Many a successful church owes its prosperity, in a great measure, to the business principles on which it is run, and its influence is made up largely of the social elements which constitute it, the numbers which attend it, or the effective machinery by which it is moved; but this may involve no spiritual power whatever.
It is not inconsistent with spiritual power; the Holy Ghost may work in the channels of order and systematic work, but all of this may exist in the most complete form and yet it be simply a religious club and ecclesiastical machinery.
A minister may build up his church just as a man builds up his business, and the ambition which accomplishes his splendid ideal may be of precisely the same kind as that which has founded and consummated the great financial enterprises of our age. There is a no more perfect organization in the world than Romanism. Its machinery is superb, but it knows nothing of spiritual power.
