Hebrews 6:4-6

Some commentators dismiss this passage because it is in a book called “Hebrews,” and they say it is only relevant for Jews, not for New Covenant believers. But notice that this describes people who have received the light of God’s truth and His Spirit.

Notice also that it does not say it is impossible to fall away, but rather that if they fall away—if they commit apostasy, or deviate from the faith and turn away from their allegiance. It says it is possible to choose that, and those who do cannot be brought back to repentance. They have publicly repudiated the Savior with their choices. The author says there is no coming back. In this way, our lives are not like gamebooks or video games, where we can start over if we reach an end we don’t like. We get one opportunity.

Hebrews 6:4-6

So David had no wish for God to leave him. He knew that if that happened it would be the end of his chance for eternal life. So he pleads for another chance. He pleads for forgiveness. I think David understood what Paul (or whoever the author of Hebrews was) writes in Hebrews 6:4-6. That once you have been enlightened, once you have tasted the heavenly gift, if it is gone, there is no further sacrifice for sin. So he was saying, "God, I still have a little bit. Help me to fill the bucket, as it were, and move forward. I don't want to have a situation in my life where You're not there."

Hebrews 6:4-6

Matthew 24:13 tells us that those who endure to the end will be saved. A lack of total commitment has terrible consequences. As Luke 9:62 says, no one who looks back is fit for the Kingdom of God. If people fall away after receiving God's Spirit, they will not repent.

The word "impossible" is used there. That is a very powerful, strong word. What a terrifying thought to consider. If they know Christ but return to the world, their end is worse than the beginning, as the apostle Peter informs us in II Peter 2:20.
