Hello CL,
God chose one nation to to place His name there.If people were going to be saved it was going to be through the Covenant made with Abraham.
Not everyone in that chosen nation was elected to salvation.
Rom .9:6-11 makes this clear...not all Israel is of Israel.
After the Cross God's elective purpose goes worldwide.
Not everyone is elect, just the multitude the Father has given to the Son.
The others are left in their natural condition.
Not predestined to hell, but left to face the White Throne Judgment and will need to be 100% sinless to make it.
None are going to, in fact.
2 Pet.3:9 teaches that God is not willing that any of the elect perish, but that All come to repentance. Not one of them will be lost.;)
