Infidelity; Its Causes, Consequences and Cure [EPUB ebook] 

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.
