Let us watch how they did it. They had been converted to the Christian faith and life. One sure effect of their conversion was a more vivid sense of sin. After their conversion their own sinfulness began to reveal itself in more awful relief. The nearer they got to the light the more their sin appeared, just like invisible writing emerging from its secrecy when exposed to the open fire. They saw their sin, and they saw the sin of the people. They were like the prophet Isaiah, to whom also there came the awakening sense of sin, and with him they could have cried: "Woe is me, for I am unclean, and I dwell in the midst of a people of unclean lips." Well, now, how could that little company of Christians deal with the sin? It was like trying to drain a vast and bitter marsh that was fed by secret springs. How could they do it? And the tremendous task only emphasized their weakness, and might have depressed them into a feeling of helplessness and despair. And we share that feeling to-day. Think of the colossal sins of Europe, and think of the sins and moral indifference of the great cities. If the sin be like a bitter marsh, what is going to drain it? Nay, how are we going to get the confidence that it can be drained? Well what did Paul do, and what did he teach his fellow-disciples to do? This is what he did. He found something even bigger than sin, and he girded himself with the bigger thing when he confronted the appalling task. Listen to him: "Where sin abounds grace does much more abound." Yes, sin is a big thing, but grace is a bigger thing; the biggest thing even in this rebellious and indifferent world. Sin is a strong thing, but grace is a stronger thing, even the strongest thing in a revolting and alienated world. Well then, let your loins be girt about with that truth! Put it around your fears and uncertainties like a strong girdle. Wear it ever night and day. Go up to every stupendous task in the vigour of its bracing grip. Begin at the piece of the bitter marsh nearest to you, and begin to drain it. And wear the truth--"Where sin abounds, grace doth much more abound." Wear the truth, say it, sing it, and you will be amazed how the difficulty will be subdued; for the mouth of the Lord hath spoken it.
