de it _certain_ that there is no future
existence; that there is no Heaven; that there is no Hell; that Jesus
was not the Saviour. The most that such writers have been able to
produce is doubts. If, now, there is _the possibility_ of reaching
_certainty_ on the other side, surely the reader should be willing
and anxious to undertake a calm, searching examination, or
re-examination, of the question. If there is no Heaven or Hell, no
future existence, no one will ever find it out, before or after death;
and there would be but little, if anything, gained if one could find
it out. But if there is a Heaven and a Hell, and Jesus is the Saviour,
then there is everything to be gained by finding it out and everything
to be lost by neglecting to find it out. So important are the issues
at stake that you, reader, should be willing to take years, if need
be, to make a thorough investigation of the matter; you should be
willing to read and study many books, and there are many that would
help you; but I wish to urge you to read _two books only_, before
reading this book. Surely your eternal destiny and the destinies of
those over whom you have an influence (for "none of us liveth to
himself") are enough to cause you to give earnest attention to the
reading of three small books. The bare possibility that the reading of
the three books may lead to your making sure of Heaven as your eternal
home, is enough to prompt you to read them and to read them most
carefully and prayerfully. The first is "The Wonders of Prophecy," by
John Urquhart. The second is "The Philosophy of the Plan of
Salvation," by J. B. Walker (American Edition). Having read these two
books prayerfully and carefully, then give this book a careful
reading.

But let the reader consider God's plan for investigating. It is often
said by a certain class of sceptics that the Bible is against honest
investigation, that it shuts off the use of one's reason. Let the
word of God speak for itself, "Come now and let us _reason_ together,
saith the Lord."--Is. 1:18. The trouble with many sceptics is that
they are not willing to "reason _together_," to reason to get with
God, but that they reason _against_ God and to _get away from God_.
Jesus said, "Take heed _how_ ye hear." Watch your heart's attitude
when you hear. The attitude of being against God will warp your
reasoning when you hear. God's promise is plain to the earnest, honest
seeker after God. "And ye shall seek me and find
