You are picking parts of Scripture out of context, and making them mean something completely different from what God intended. Anyone can do that, but when we do that to God's own word, then that is sad.
Hebrews 10:10 (WEB)
10 by which will
we have been sanctified through the offering of the body of Jesus Christ once for all.
Who does God sanctify? God sanctifies
WE Christians - those who believe.
Acts 26:17-18 (NIV)
17 I will rescue you from your own people and from the Gentiles. I am sending you to them 18 to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those
who are sanctified by faith in me.
A Christian is a disciple of Lord Jesus, so if you faith does not lead you to listen to and follow Lord Jesus, then you are not sanctified or saved.
Acts 11:26 (NIV)
The
disciples were called
Christians first at Antioch.
Matthew 28:19-20 (NIV) 19 Therefore go and
make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and
teaching them to obey everything I have commanded you.
Hebrews 10:14 (WEB)
14 For by one sacrifice he has made perfect forever those
who are being made holy.
IF you are being made holy now, then the sacrifice of Lord Jesus has made perfect.
However, in the very same letter, and the very same chapter to the Hebrews, we learn that not all Christians continue to be made holy because of deliberate sin. In this case, God will punish them with everlasting fire.
Hebrews 10:24-30 (WEB)
24
Let us consider how to provoke one another to love and good works, 25 not forsaking our own assembling together, as the custom of some is, but exhorting one another, and so much the more as you see the Day approaching. 26
For if we sin willfully after we have received the knowledge of the truth, there remains no more a sacrifice for sins, 27 but a c
ertain fearful expectation of judgment, and a fierceness of fire which will devour the adversaries. 28 A man who disregards Moses’ law dies without compassion on the word of two or three witnesses. 29
How much worse punishment do you think he will be judged worthy of who has trodden under foot the Son of God, and has
counted the blood of the covenant with which he was sanctified an unholy thing, and has
insulted the Spirit of grace? 30 For we know him who said, “Vengeance belongs to me. I will repay,” says the Lord. [
Deuteronomy 32:35] Again, “
The Lord will judge HIS people.” [
Deuteronomy 32:36;
Psalm 135:14] 31 It is a fearful thing to fall into the hands of the living God.
