I am not perplexed with doubt, because the truth which I believe has wrought a miracle on me. By its means I have received and still retain a new life, to which I was once a stranger: and this is confirmation of the strongest sort. I am like the good man and his wife who had kept a lighthouse for years. A visitor, who came to see the lighthouse, looking out from the window over the waste of waters, asked the good woman, "Are you not afraid at night, when the storm is out, and the big waves dash right over the lantern? Do you not fear that the lighthouse, and all that is in it, will be carried away? I am sure I should be afraid to trust myself in a slender tower in the midst of the great billows." The woman remarked that the idea never occurred to her now. She had lived there so long that she felt as safe on the lone rock as ever she did when she lived on the mainland. As for her husband, when asked if he did not feel anxious when the wind blew a hurricane, he answered, "Yes, I feel anxious to keep the lamps well trimmed, and the light burning, lest any vessel should be wrecked." As to anxiety about the safety of the lighthouse, or his own personal security in it, he had outlived all that. Even so it is with the full-grown believer. He can humbly say, "I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day." From henceforth let no man trouble me with doubts and questionings; I bear in my soul the proofs of the Spirit's truth and power, and I will have none of your artful reasonings. The gospel to me is truth: I am content to perish if it be not true. I risk my soul's eternal fate upon the truth of the gospel, and I know that there is no risk in it. My one concern is to keep the lights burning, that I may thereby benefit others. Only let the Lord give me oil enough to feed my lamp, so that I may cast a ray across the dark and treacherous sea of life, and I am well content. Now, troubled seeker, if it be so, that your minister, and many others in whom you confide, have found perfect peace and rest in the gospel, why should not you? Is the Spirit of the Lord straitened? Do not his words do good to them that walk uprightly? Will not you also try their saving virtue? Most true is the gospel, for God is its Author. Believe it. Most able is the Saviour, for he is the Son of God. Trust him. Most powerful is his precious blood. Look to it for pardon. Most loving is his gracious heart. Run to it at once.
