On Learning from Unbelievers

Spurgeon says you can learn much from unbelievers. I totally agree. From Lectures to My Students, p. 211:

I have seen very much of my own stupidity while in conversation with seeking souls. I have been baffled by a poor lad while trying to bring him to the Saviour; I thought I had him fast, but he has eluded me again and again with perverse ingenuity of unbelief. Sometimes inquirers who are really anxious surprise me with their singular skill in battling against hope; their arguments are endless and their difficulties countless. They put us to a non plus again and again. The grace of God at last enables us to bring them to the light, but not until we have seen our own inefficiency. In the strange perversities of unbelief, the singular constructions and misconstructions which the desponding put upon their feelings and upon scriptural statements, you will often find a world of instruction. I would sooner give a young man an hour with inquirers and the mentally depressed than a week in the best of our classes.
