R. A. Torrey 
Infidelity; Its Causes, Consequences and Cure 

The profession of infidelity is very common in our day. I am constantly meeting with those who give as their reason for not being Christians that they do not believe in the Bible. There are many preachers, most excellent and gifted men, who think that infidelity is not worthy of attention, that the proper way to treat it is to ignore it. I do not agree with them. Infidelity is common enough, and active enough, and destructive enough to demand attention. While I do not for a moment think that the cause of Christ or the Bible has anything to fear from infidelity, I do know that individuals and communities are being greatly injured by it, and we owe it to them to expose its real character, to point out its consequences, and to show its cure.

I have had no greater joy now for some years than to be able to lead many men out of the confusion and wretchedness of infidelity into the clear light and abounding joy of an intelligent faith in Christ and the Bible.
