"Well, dear friends, you know that some men can do to the glory of God what to other men would be sin. And notwithstanding what brother Pentecost has said, I intend to smoke a good cigar to the glory of God before I go to bed to-night.
"If anybody can show me in the Bible the command, 'Thou shalt not smoke,' I am ready to keep it; but I haven't found it yet. I find ten commandments, and it's as much as I can do to keep them; and I've no desire to make them into eleven or twelve.
"The fact is, I have been speaking to you about real sins, not about listening to mere quibbles and scruples. At the same time, I know that what a man believes to be sin becomes a sin to him, and he must give it up. 'Whatsoever is not of faith is sin' [Rom. 14:23], and that is the real point of what my brother Pentecost has been saying.
"Why, a man may think it a sin to have his boots blacked. Well, then, let him give it up, and have them whitewashed. I wish to say that I'm not ashamed of anything whatever that I do, and I don't feel that smoking makes me ashamed, and therefore I mean to smoke to the glory of God."
