A few have even taken the absurd position that a born-again person may ultimately turn away from Christ into unbelief, deny God, and become an atheist — yet still possess eternal life. One writer invented a term for such people: "unbelieving believers"! 

Scripture is clear that a saved person can never be lost. It is equally clear that a genuine Christian will never fall back into total unbelief. That kind of apostasy proves an individual was never really born again (1 John 2:19). 

Furthermore, if a person is genuinely saved, his life will change for the better (2 Corinthians 5:17). He is saved "for good works" (Ephesians 2:10), and there is no way he can fail to bring forth at least some of the fruit that characterizes the redeemed (cf. Matthew 7:17). His desires are transformed; he begins to hate sin and love righteousness. He will not be sinless, but the pattern of his life will be decreasing sin and increasing righteousness. 

You need to settle these critical questions in your own heart. Study the gospel Scripture presents. Listen with discernment to every speaker you hear. Measure everything by the Word of God. Above all, make sure that the message you share with unbelievers is truly the gospel of Christ.
