Witnessing to the Indifferent

Following is a story in Spurgeon's own words of sharing the gospel with someone who agreed with everything he said but was not a believer:

"I had once to deal with a man who assented to everything I said. When I talked about the evil of sin, he agreed with me, and said that I was very faithful. When I set before him the way of salvation, he assented to it, but it was evident that his heart was not affected by the truth. I could almost have wished that he had flatly denied what I said, for that would have given me the opportunity of arguing the matter with him, and pressing him to come to a decision. At last, I felt that it was quite hopeless to talk to hint any longer, so I said, 'The fact is, one of these days you will die, and be damned,' - and I walked away without saying another word. As I expected, it was not very long before he sent for me, and when I went to him, he begged me to tell him why I had said such a dreadful thing to him. I answered, 'It seems quite useless for me to talk to you about the salvation of your soul, for you never appear to feel the force of anything that I say. I might almost as well pour oil down a slab of marble as expect you to be impressed by the truth that I set before you, and my solid conviction is that you will be damned.' He was quite angry with me for speaking so plainly; and I went away again, leaving him very cross. Before many hours were over, he was in all awful state of mind; the Holy Spirit had convinced him of his state as a sinner, and he was in an agony of soul. That sharp sentence of mine was like the hook in a fish's gills, but that fish was landed all right. The man was brought to repentance and faith; he was baptized, joined the church, and a few years ago went home to Heaven"
