Come unto Me, all ye that labour and are heavy laden, and I will give you rest. – Matthew 11:28

This morning, I got, from a friend who came in to see me, an illustration which I will give to you. He told me-and oh, how he made my heart rejoice!-that, six years ago, he was, so the apostle says, “going about to establish his own righteousness.” He is a man of reputation, and when a friend sent him some of my sermons to read, he thought to himself, “What do I want these sermons for? I am as good as any man can be.” But he did read them, and the friend asked him, “Have you read those sermons of Mr. Spurgeon’s that I sent you?” “Yes,” he replied, “I have; but I have got no good out of them.” “Why not?” “Why,” he said, “he has spoiled me; he has dashed my hopes to the ground, he has taken away my comfort and my joy; I thought myself as good as anybody living, and he has made me feel as if I were rotten right through.” “Oh!” said his friend, “that medicine is working well, you must take some more of it.” But the more of the sermons he read, the more unhappy he became, the more he saw the hollowness of all his former hopes; and he came into a great darkness, and the day did not break, and the shadows did not flee away. But, on a sudden, he was brought out into the light. As he told me the story, this morning, his eyes were wet, and so were mine. This is how the Lord led him into peace; I wish the telling of it might bring the same blessing to some of you. He said, “I went with my friend to fish for salmon in Loch Awe. I threw a fly, and as I threw it, a fish leaped up, and took it in a moment.” “There,” said the friend to him, “that is what you have to do with Christ, what that fish did with your fly. I am sure I do not know whether the fly took the fish, or the fish took the fly; it was both, the bait took the fish, and the fish took the bait. Do just so with Christ, and do not ask any questions. Leap up at Him, take Him in, lay hold of Him.” The man did so, and at once he was saved; I wish that somebody else would do the same. I never ask you to answer the question whether it is Christ who takes you or you who take Christ, for both things will happen at the same moment. Will you have Him? Will you have Him? If you will have Him, He has you.  ~ C.H.Spurgeon
