hello JLB, dirtfarmer here
Ishmael was Abraham's first born according to the flesh, but Isaac was the first born according to faith, the son of promise.
Genesis 22:2 "And he said, Take now they son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; offer him there for a burnt offering upon one of the mountains which I will tell the of."
WE all know that Isaac was Abraham's son by promise.
The point we are discussing is this statement:
For they are not all Israel who are of Israel.
Ishmael was Abraham's son, not Jacob's [Israel].
The point is not all who are Israel [
after the flesh] are Israel.
Christ Jesus is the True Israel of God.
Those who are in Covenant with Christ, the True Israel are Israel [the true Israel of God].
I tell the truth in Christ, I am not lying, my conscience also bearing me witness in the Holy Spirit, 2 that I have great sorrow and continual grief in my heart. 3 For I could wish that I myself were accursed from Christ for my brethren, my countrymen according to the flesh, 4 who are Israelites, to whom
pertain the adoption, the glory, the covenants, the giving of the law, the service
of God, and the promises; 5 of whom
are the fathers and from whom, according to the flesh, Christ
came, who is over all,
the eternally blessed God. Amen.
6 But it is not that the word of God has taken no effect. For they
are not all Israel who
are of Israel, 7 nor
are they all children because they are the seed of Abraham; but, “In Isaac your seed shall be called.”8 That is, those who
are the children of the flesh, these
are not the children of God; but the children of the promise are counted as the seed. 9 For this
is the word of promise: “At this time I will come and Sarah shall have a son.” 10
And not only this, but when Rebecca also had conceived by one man,
even by our father Isaac 11 (for
the children not yet being born, nor having done any good or evil, that the purpose of God according to election might stand, not of works but of Him who calls), 12 it was said to her, “The older shall serve the younger.”13
As it is written, “Jacob I have loved, but Esau I have hated.” Romans 9:1-13
Paul is showing the election of God according to purpose.
Christ is the eternal purpose of God.
He shows the lineage whom God would use to bring the Messiah into the world was through the descendant's of Abraham, but more specifically through the children of promise, that is to say, those whom God choose...
Abraham, Isaac and Jacob, then Judah.
In the middle of this discourse Paul, makes his statement...
For they are not all Israel who are of Israel.
Ishmael was Abraham's son, not Jacob's [Israel].
Christ is the Israel of God, and those who are joined to him in covenant relationship are the Israel of God.
Then you shall say to Pharaoh, ‘Thus says the Lord:
“Israel is My son, My firstborn.Exodus 4:22
“When Israel
was a child, I loved him, And out of Egypt
I called My son.
Hosea 11:1
These are prophetic references to Christ, God's Firstborn... meaning these references in the old testament pointed to Christ, as God's firstborn Son.
13 Now when they had departed, behold, an angel of the Lord appeared to Joseph in a dream, saying, “Arise, take the young Child and His mother, flee to Egypt, and stay there until I bring you word; for Herod will seek the young Child to destroy Him.”
14 When he arose, he took the young Child and His mother by night and departed for Egypt, 15 and was there until the death of Herod,
that it might be fulfilled which was spoken by the Lord through the prophet, saying, “Out of Egypt I called My Son.”
Matthew 2:13-15
