The gospel in vogue today holds forth a false hope to sinners. It promises them that they can have eternal life yet continue to live in rebellion against God. Indeed, it encourages people to claim Jesus as Savior yet defer until later the commitment to obey Him as Lord. It promises salvation from hell but not necessarily freedom from iniquity. It offers false security to people who revel in the sins of the flesh and spurn the way of holiness. By separating faith from faithfulness, it teaches that intellectual assent is as valid as a wholehearted obedience to the truth.
Thus the good news of Christ has given way to the bad news of an insidious easy-believism that makes no moral demands on the lives of sinners. It is not the same message Jesus proclaimed.
