It sounds like that is as close to coming to the truth as you will get.
It's your argument that is inaccurate. See post #685.
You still just DON'T GET IT and those who drew back to perdition and did not believe to the saving of the soul (vs. 39) were never sanctified "set apart" as genuine believers (who believed to the saving of the soul) but were "set apart" as professing believers/active participants in the Hebrew Christian community of genuine believers. Those who drew back to perdition did not "temporarily" believe to the saving of the soul either, which is just NOSAS smoke and mirrors. Feel free to go back and read post #19 until the truth finally sinks in - https://christianchat.com/bible-discussion-forum/that-hebrews-10v26-thread.189675/
Hebrews 10:10 - By this will
WE have been sanctified through the offering of the body of Jesus Christ
ONCE FOR ALL.
Hebrews 10:14 - For by one offering He has
perfected FOR ALL TIME THOSE who are sanctified.
Does that permanent or temporary? It's
permanent for genuine believers, but
not for those with
spurious faith who draw back to perdition and do not believe to the saving of the soul. (vs. 39)
I guess you will just have to live with your
contradiction in Hebrews 10:29. Whether you like it or not,
there are genuine Christians and there "nominal" Christians. There are genuine believers and there are "make" believers.
In Hebrews 10:26, To "sin willfully" in the Greek carries the idea of deliberate intention that is habitual, which
stems from rejecting Christ deliberately. This is continuous action, a matter of
practice. Now we don't walk along our daily life and "accidentally" fall into a pit called sin. We exercise our will but, the use of the participle shows willful, habitual continuous action. The
unrighteous practice sin (1 Corinthians 6:9-10; Galatians 5:19-21);
not the righteous, who are born of God (1 Corinthians 6:11; 1 John 3:9). Another
contradiction that you will have to live with. *You need to properly harmonize scripture with scripture before reaching your conclusion on doctrine.*
