These concepts are not in my bible. Nor do I see any reason to accept the Christian scriptures as canonical.
I have no intention of trying to forcibly convince you or anyone on this truth. When you study the Word and do not literaly take things out of context, you come to discernment with much prayer of course for discernment.
Yes, Bible does back this up. Read what " chosen " means from for example, Strong's concordance, study the word "gentile," the word "elect" . Then you pray for discernment and you will see the " whole picture" not just one verse out of context.
If you do not see this as truth, then what can I say. So be it.
Peace.
