Churchgoers and pastors around the world have slowly abandoned the doctrine that Jesus Christ taught His disciples to teach unbelievers, which is repentance (i.e. godly sorrow) for the remission (i.e. forgiveness/pardoning) of sin.
"Then opened he their understanding, that they might understand the scriptures, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem." -Luke 24:45-47
Because of this, countless false converts have been created through a commonly used "sinner's prayer" that has never saved anyone. In this book, we learn the core doctrine of repentance in Scripture, that the Bible teaches it is a gift from God, how it is taught completely wrong in most church buildings, and that few churchgoers and pastors have ever had a contrite spirit of humility.
"The LORD is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit." -Psalm 34:18
