A Warning for Believers? Hebrews 6:4–6 Explained

Can a Christian lose their salvation?

Posted on August 6, 2026 by Paul Ellis // 0 Comments

Is salvation a once and for all time deal? Is it a case of once saved, always saved? What does the Bible say? Some verses say yes, while others say no. How do we reconcile these apparent inconsistencies?

Well, it’s quite easy when you realize that there are more than 100 scriptures guaranteeing the eternal security of the believer. Those in Christ are eternally secure.

And how many scriptures say otherwise? Not one. There are only scriptures that are misunderstood or taken out of context and which are sometimes used to frighten Christians. Like this one:

It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, who have tasted the goodness of the word of God and the powers of the coming age and who have fallen away, to be brought back to repentance. To their loss they are crucifying the Son of God all over again and subjecting him to public disgrace. (Hebrews 6:4–6, NIV)

These words were not written to Christians; they are a warning for those who reject Jesus. In context, this warning was directed to those Jews who witnessed the ministry and death of Jesus Christ, and then carried on as though nothing had changed.

Imagine what it would’ve been like to see Jesus heal the sick and raise the dead. Imagine watching him feed the 5,000 with a boy’s lunch or cast demons out of the oppressed. The first-century Jews were privileged above all people to have a front-row seat to the supernatural ministry of the Son of God.

And yet despite seeing all these things and hearing the gospel straight from his lips, most did not believe him. “I have come in My Father’s name,” said Jesus, “and you do not receive me” (John 5:43). The Jews saw the Light of God and tasted the heavenly gift, but they shut their eyes and wanted nothing to do with him. Hence the warning of Hebrews 6.

Consider Jesus

In Hebrews, we are invited to “consider Jesus, the apostle and high priest of our confession” (Heb. 3:1). In other words, look at Jesus. Consider who he is and why he came. Don’t be one of those who:

have heard the gospel but have not responded with faith (Heb. 4:2, 11)
are slow to learn and dull of hearing (Heb. 5:11)
remain unacquainted with the teaching about righteousness (Heb. 5:13)

If you are like those Jewish unbelievers who rejected Jesus, the message of Hebrews is:

pay much closer attention to what you have heard (the gospel) (Heb 2:1)
don’t neglect God’s offer of salvation (Heb. 2:3)
don’t be one of those who has an evil and unbelieving heart (Heb. 3:12)

This message had special relevance for the Jews because of the hard lessons set by their forefathers, who hardened their hearts and died in the wilderness (Heb. 3:8–11). “Don’t be like them.” They never entered God’s rest because of unbelief (Heb. 3:19).

Restless unbelievers

It’s important to remember that Hebrews, like the epistle of James, was written to a broad Jewish audience. The author was writing to both encourage Jews who were believers (e.g., Heb. 12:1–2) and warn those who were still making up their minds (e.g., Heb. 3:8, 12).

Two audiences mean two messages. And it’s important to distinguish these, otherwise you could end up taking someone else’s medicine.

Warnings like “how will we escape if we neglect so great a salvation?” (Heb. 2:3) and “do not harden your hearts” (Heb. 3:8) are plainly not meant for believers. Believers don’t have “evil, unbelieving hearts” (Heb. 3:12). With this in mind, let’s take a closer look at Hebrews 6:

Those who have once been enlightened…

Jesus is the Light of the world who gives light to everyone, including those who prefer the darkness (John 1:9, 3:19).

…who have shared in the Holy Spirit…

The Jews saw Jesus ministering with supernatural signs and wonders. Many experienced healing and deliverance, and some even saw the risen Lord. They tasted the powers of the coming age, and yet they turned their backs on the Lord.

and then have fallen away…

This is not talking about believers who stumble in sin, but unbelievers who come short of the grace of God (see Heb. 12:15). In context, it’s referring to those who witnessed Jesus and the ministry of the Holy Spirit, but turned back to the old ways of the temple. They had more faith in the sacrifices of dead animals than in a risen Savior.

It is impossible … to be brought back to repentance

Those who have hardened their hearts to the gospel are well and truly lost. To hear the good news of Jesus and scorn him is fatal, for salvation is found in no other name (Acts 4:12). God has no Plan B. No back-up savior is waiting in the wings to rescue you. It’s Jesus or nothing.

They are crucifying the Son of God all over again and subjecting him to public disgrace.

Put your faith in religion and dead works (e.g., sin confession) and you are essentially saying Christ’s sacrifice was insufficient. Jesus needs to die again. Once was not enough. It is a shameful dismissal of God’s Son and his perfect sacrifice.

Better things, beloved

But, beloved, we are convinced of better things concerning you, and things that accompany salvation, though we are speaking in this way. (Hebrews 6:9)

The author of Hebrews, now addressing his fellow believers, finishes on a positive note. “I am convinced that you are not like those who turn their backs on God’s Son. I know you have received the blessings that accompany salvation.”

And so we have!
