The title is meant to get your attention. However, it is very true that only trusting Christ will not bring about the new birth. The devil has managed to water down the Gospel until most only believe half of it. It is repentance toward God and faith in the Lord Jesus Christ that brings about salvation. Repentance alone will not save anyone, but neither will simply "trusting" Christ for a better life, and a home in heaven when you die. Multitudes, in fact, most of the human race is going to be lost for eternity because they did not turn from their sin to trust in Christ. There is no such thing as saving faith in Christ while you continue in sin; continue being the same person you have always been; continue in hatred and strife and bitterness.
