A. H. Strong, in his 1905 sermon in London:
How shall I, how shall society, find healing and Purification within? Let me answer by reminding you of what they did at Chicago.
In all the world there was no river more stagnant and fetid than was Chicago River. Its sluggish stream received the sweepings of the watercraft and the offal of the city, and there was no current to carry the detritus away. There it settled, and bred miasma and fever.
At last it was suggested that, by cutting through the low ridge between the city and the Des Plaines River, the current could be set running in the opposite direction, and drainage could be secured into the Illinois River and the great Mississippi. At a cost of fifteen millions of dollars the cut was made, and now all the water of Lake Michigan can be relied upon to cleanse that turbid stream.
What the Chicago River could never do for itself, the great lake now does for it. So no human soul can purge itself of its sin; and what the individual cannot do, humanity at large is powerless to accomplish.
Sin has dominion over us, and we are foul to the very depths of our being, until with the help of God we break through the barrier of our self-will, and let the floods of Christ’s purifying life flow into us. Then, in an hour, more is done to renew, than all our efforts for years had effected. Thus humanity is saved, individual by individual, not by philosophy, or philanthropy, or self-development, or self-reformation, but simply by joining itself to Jesus Christ, and by being filled in Him with all the fulness of God.
