Is it possible for Christians to fall away from the faith? This is one of the questions I hear over and over again as a pastor, and I’ve wrestled with it myself:

• “My cousin was baptized when she was 10 but now she wants nothing to do with Jesus. Did she lose her salvation?”
• “I’ve been following Christ for 17 years, but how do I know I won’t end up falling away at some point in the future?”
• “Did you hear about _________ [famous preacher who walked away from God]? If he can lose his faith, how can any of us assume that we won’t lose ours?”

Sometimes our experiences or perceptions seem to contradict what we were taught in church or what we read in the pages of Scripture. But “all Scripture is God-breathed.” It is the final authority and ultimate standard when it comes to this question. So what does the Bible say? Is it possible for Christians to fall away from the faith?

First, understand that it is possible to have a kind of faith that looks real for a while but is actually fake. Consider Jesus’ parable of the four soils (Matthew 13:1-23). Jesus describes two types of soil (rocky and thorny) in which a seed germinates but the plant dies before it comes of age.

These two types of soil are a metaphor for two different responses to the message of the gospel. Sometimes, a person hears the gospel and has a sort of faith: they respond positively to the message. They believe it—to a point. But then life’s trials (the rocks) or temptations (the thorns) choke this ungrounded faith to death.

In other words, they have faith, but not saving faith. It’s a superficial faith that doesn’t last.

This is the kind of faith that Judas had. He didn’t set out to betray Jesus initially. He followed him and listened to his teaching. He agreed with his mission—to a point. But time revealed the truth: his faith was merely superficial; it was not saving faith.

Many who “fall away” are in this category. They believe the gospel, but their belief is merely superficial. It has no roots, and because it has no roots, it does not last. In such cases, it’s not that a genuine, born-again believer in Christ—someone who has the indwelling Holy Spirit and possesses eternal life—loses his or her salvation. It’s that the appearance of faith eventually gives way to a sobering reality: such faith was never real to begin with.

Second, remember that a person’s heart is both difficult to understand and frustratingly deceptive. To even begin to plumb the depths of someone’s heart takes great wisdom (Proverbs 20:5). But keep in mind, the heart (in the case of an unbeliever) is deceitful above all things and desperately sick (Jeremiah 17:9), so deceptive that a person can deceive even himself (James 1:22).

The point I’m making is that it’s possible for a person to think he has faith when in fact he does not. It’s also possible to think another person is a true believer when in fact he is not. We’re not the ultimate Judge of these things and therefore we should not be surprised if our perceptions turn out to be mistaken: The person who “loses” his salvation may just be a person we didn’t know as well as we thought.

Third, accept the fact that those who “leave” the faith only do so because they were never really believers to begin with. This is the unavoidable meaning of 1 John 2:18-19, in which John explains, “If they had been of us, they would have continued with us.”

Finally, take refuge in the fact that a true Christian—a man or woman who has genuine faith and is born again by the power of the Holy Spirit—will never fall away because Jesus himself will see to it that such a person remains in Him. As Jesus says in John 10, “My sheep . . . will never perish, and no one will snatch them out of my hand.”

Don’t overcomplicate this. Jesus is as straightforward as possible: They will never perish. “I understand that no one can take them out of Jesus’ hand, but what if they leave by their own free will?” This will not happen. They will never perish. Jesus does not leave any room for exceptions. He says what He means.

If you are a believer in Christ, you cannot fall away. Christ will make sure that you do not. He guarantees it by His Word and He makes sure of it through the ministry of His Holy Spirit.

Take heart. Be confident. Rest in the certainty of your salvation. It’s as sure as the unchanging and all-powerful promise of our loving Savior!
