That if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation. 11 For the Scripture says, “WHOEVER BELIEVES IN HIM WILL NOT BE DISAPPOINTED.” Romans 10:9-11
We may live in a culture that believes everyone will be saved, that we are “justified by death” and all you need to do to go to heaven is die, but God’s Word certainly doesn’t give us the luxury of believing that. Any quick and honest reading of the New Testament shows that the Apostles were convinced that nobody can go to heaven unless they believe in Christ alone for their salvation (John 14:6; Rom. 10:9–10).
Historically, evangelical Christians have largely agreed on this point. Where they have differed has been on the matter of the security of salvation. People who would otherwise agree that only those who trust in Jesus will be saved have disagreed on whether anyone who truly believes in Christ can lose his salvation.
Theologically speaking, what we are talking about here is the concept of apostasy. This term comes from a Greek word that means “to stand away from.” When we talk about those who have become apostate or have committed apostasy, we’re talking about those who have fallen from the faith or at least from the profession of faith in Christ that they once made.
