Not only close, but a bullseye.
So your sanctified person in Hebrews 10:29 doesn't even exist! God doesn't sanctify (set apart as clean) fake believers in the church.
In 1 Corinthians 7:14, Paul uses the term "sanctified" to specifically refer to non-Christians who are
"sanctified" or
"set apart" by their believing spouse.
(And by this Paul does not mean that they are saved). A non-Christian can be "set apart" from other non-Christians without experiencing salvation as Paul explained and once again, if the word 'sanctified' in Hebrews 10:29 is used to describe saved people who lost their salvation (as eternal IN-securists teach), then we have a
contradiction because the writer of Hebrews in verse 10 said
"sanctified through the offering of the body of Jesus Christ once for all" (Hebrews 10:10) and in verse 14, we read,
"perfected for all time those who are sanctified." (Hebrews 10:14) This is not temporary. Open your eyes!
Read it with me. In Hebrews 10:10, we clearly read
..WE have been sanctified through the offering of the body of Jesus Christ once for all. In Hebrews 10:14, we read - For by one offering He has
perfected for all time THOSE who are sanctified. To go from sanctified back to un-sanctified would be in contradiction here, so those Hebrews who were "set apart," but not saved, (vs. 29) drew back to perdition and
DID NOT BELIEVE TO THE SAVING OF THE SOUL. (vs. 39)
Reformed theologians, who should know better, invented a sanctified person in the church that doesn't even exist! And they did it to avoid the obvious non-osas message of Hebrews 10. Shame on them. They have led millions astray.
That's just your pride speaking. Your arguments have been refuted numerous times, but you are too stubborn to admit your error and accept the truth. You have your agenda.
