1Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
2Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
3And this will we do, if God permit.
4For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
5And have tasted the good word of God, and the powers of the world to come, 6If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
If it not possible to fall away, then why would this verse be in the Bible?
I believe this passage in the bible has many miss conceptions about it, yes, it is speaking of salvation but not necessarily the loss of it, really I believe it speaks of works we have done after receiving salvation.
First of all let us go on and read the rest of the passage:
"For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God."
If you read this verse carefully you can see that it is speaking of works
after we are saved.
"but if it bears thorns and briers, it is rejected
and near to being cursed, whose end is to burned."
I don't think we can ever truly lose our salvation, if in fact we were truly saved to begin with, which this passage is speaking of. I believe though that the passage is speaking of our works that will be judged with fire as in 1 Corinthians 3:
13 "each ones works will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one's work, of what sort it is.
14 If anyone's work which he has built on it endures, he will receive a reward.
15 If anyone's work is burned, he will suffer loss;
but he himself will be saved, yet so as through fire."
Now if you go on in Hebrews to the next verses after the ones I posted above you will see the explanation of the warning:
9 "But beloved, we are confident of better things concerning you, yes, things that
accompany salvation, though we speak in this manner.
10 For God is not unjust to forget
your work and labor of love which you have shown toward His name, in that you have ministered to the saints, and do minister."
In my opinion this verse is concerning those who have become sluggish in regards to works for the Kingdom of God, it is not saying we can lose our salvation but it is saying we can lose our rewards if we continue in such a manner, our works will be burned with the holy fire of God, if they are not approved then they will be burned but although near a curse the person still will be saved, yet as so by fire.
to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
This also shows that if we fall away it ruins our testimony for the Lord, for if we backslide we are putting Jesus Christ through an open shame, an example of this is pastors who have been caught with prostitutes, ect.
I do not think such people can lose their salvation but their works will be burned, and they will not be able again to repent in the manner where they then again can earn crowns and rewards through works, their repentance is ruined and they have shamed the One who has saved them and sanctified them.
