I know that this is the OSAS belief about the matter.
But for me, Hebrews 10 makes it crystal clear what will happen to the 'wife' sanctified (cleansed and made holy) by the blood who then tramples on that blood in a willful, unbelieving sinning:
10 By this will we have been sanctified through the offering of the body of Jesus Christ once for all.
14 For by one offering He has perfected for all time those who are sanctified. 15And the Holy Spirit also testifies to us; for after saying,
23 Let us hold fast the confession of our hope without wavering, for He who promised is faithful; 24and let us consider how to stimulate one another to love and good deeds, 25not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the more as you see the day drawing near.
26 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins,
27 but a terrifying expectation of judgment and THE FURY OF A FIRE WHICH WILL CONSUME THE ADVERSARIES.
28 Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses.
29 How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
30 For we know Him who said, “VENGEANCE IS MINE, I WILL REPAY.” And again, “THE LORD WILL JUDGE HIS PEOPLE.”
31 It is a terrifying thing to fall into the hands of the living God.
Hebrews 10:10,14,23,26,27,28,29,30,31 (Caps and italics in original)
I'm done letting the church tell me the Bible doesn't really mean what it says.
How can you just look past these plain words except that you've been taught not to see them by OSAS?
The person sanctified by the blood of Christ who then tramples on that blood and insults the Spirit of grace in a willful, unbelieving sinning
will go to hell. They do not get to keep the sanctification they have received in Christ.
How can you not see this?
