Evidence of Genuine Conversion

There is an Old Testament verse that describes the majority of the world's population in regards to saving faith in the one true God:
"Multitudes, multitudes in the valley of decision" (Joel 3:14).
This is very sad, but equally sad is a serious condition, not outside, but inside the Church.
A one word change in the above verse would make it read:
"Multitudes, multitudes in the valley of [deception]."
This one word change aptly describes the "serious condition" mentioned above, a condition which this book addresses.
Being in the right religion, and acknowledging Christ as the one and only Savior of mankind, is, according to the Bible, the only way to heaven and eternal life. But within the Church not all who profess Christ, have Christ. There are "multitudes" of professing Christians who feel secure about their eternal destiny but, unknown to them; they are in the "valley of [deception]."
What are the causes of this alarming, soul damning, condition, and how can we know if we ourselves have been deceived about the true state of our spiritual condition?
No matter how secure you believe you are in your faith this is a book you need to read. The Word of God commands us to "Examine yourselves to see whether you are in the faith, prove yourselves" (2 Corinthians 13:5). This command was given by God to every person, and if you have never obeyed the Lord in this command then now is the time to do so. None of God's commands are optional.
This book will aid you in obeying the Lord in this regard, and if yours was a genuine conversion experience the end result of your obedience will be a sweet confirmation and strengthening of your faith. On the other hand, should you be among the "multitudes" within the Church who are unknowingly deceived concerning your salvation experience then this book could mean the difference between heaven and hell!
