SUPPOSE you see a lake, and there are twenty or thirty streamlets running from it: why, there will not be one strong river in the whole country; there will be a number of little brooks which will be dried up in the summer, and will be temporary torrents in the winter. They will every one of them be useless for any great purpose, because there is not water enough in the lake to feed more than one great stream. Now, a man’s heart has only enough life in it to pursue one object fully. Ye must not give half your love to Christ, and the other half to the world. No man can serve God and mammon.
