In one of his Epistles St. Paul has a remarkable passage about working for God. He tells us that god and we are co workers, and that we can do nothing without Him. This is true even in our common affairs. In a little shop on a back street a man makes a mariner’s compass. It is taken on board a great ship, and by means of its trembling needle the vessel is guided over the sea unerringly to its destination. A man made the compass. Yes; a man and God. A man did the mechanical work, put the wonderful instrument together; but it was God who put into the magnet its mysterious power. This illustrates a common law. God and man are co-worker; and without God man can do nothing, while God’s perfect work needs man’s best.
