I have no idea what you are saying Nanna because it is not found in the NT. Instead there are two things that touch on this quite differently: Christ is the believer's authority, and the nations come into the promises to Israel through Christ's Gospel.
I don't find any residual regard for Israel as a nation in the NT. Those Romans passages are there to show that yes, some of them (from Israel) will believe the Gospel, and there would be an advantage because of their background. But readers keep trying to make this all or nothing. God is not all or nothing with any ethnos on earth; he is with those who have faith in the Gospel.
through his gift his blood we have only been anointed king( children of the kingdom)......
then starts the rest of the process which puts in us all the things which we do not posses which is actually 'salvation....' because no one who is a usurper will even enter the 8thday much less the 7th day of rest/ peace..
just because your 'father is peace' don't mean you/we are peace !
Jesus does not steal anyones authority, never has.. that is what free will is all about . it is God not stealing what is not his to take..
he demands we offer him our gifts and our own authority free will........ he steals nothing.. he usurps no one... he blesses and blesses and blesses , rain and sun on the evil and the good....now.. even if he has to cut a garment ( his own ) to prove that he loves us he will take nothing . though he sure can take anytime he wants, but he won't do it.
he is lawful! he is holy!
is the church so used to thieving the gifts and authorities from other nations and peoples tribes and even other churches.. is that only what we/ they know? that is not the stuff of jesus when we do it.
we command God like he is our puppy..
we usurped other churches and god' promises to others ...
NO Absalom will not inherit period.
your father may be peace, but that don't mean that is who you/we are!
bless what he blesses!
