Paul must not have known all that when he wrote his epistles to the “Hebrews”, warning them against apostatizing to Judaism and dooming themselves.
If one interprets the passages in Hebrews as indicating you can lose your salvation one must also recognize you cannot get it back.
I agree - if we could not lose our salvation, then we would have to have lost our freedom of choice - and without freedom of choice we cannot Love - because Love - real Love - is a choice. This is the reason we live - to choose Love!
The writers of the Bible were writing the words Go0d spoke for them to write.
MY Bible has no words given by flesh.
Even though evidentially it is unlikely Paul wrote it, but God inspired it.
Hebrews was written to Hebrews, not to Gentile Christians who might become Jews. It was written to convince the Hebrews of the “better” (the word used prolifically through the book) things in Christ. It was to pull Hebrews over the line into the sufficiency of Christ. It is not a treatise on Christians “losing” their salvation.
