God is God of all people and all nations are blessed through Abraham and his faith. He is the father of all who have and live by faith.
Here are some passages. Of course you don't agree with the interpretation of these verses.
Isa 42:1“Here is my servant, whom I uphold,
my chosen one in whom I delight;
I will put my Spirit on him,
and he will bring justice to the nations.
2 He will not shout or cry out,
or raise his voice in the streets.
3 A bruised reed he will not break,
and a smoldering wick he will not snuff out.
In faithfulness he will bring forth justice;
4 he will not falter or be discouraged
till he establishes justice on earth.
In his teaching the islands will put their hope.”
5 This is what God the Lord says—
the Creator of the heavens, who stretches them out,
who spreads out the earth with all that springs from it,
who gives breath to its people,
and life to those who walk on it:
6 “I, the Lord, have called you in righteousness;
I will take hold of your hand.
I will keep you and will make you
to be a covenant for the people
and a light for the Gentiles,
7 to open eyes that are blind,
to free captives from prison
and to release from the dungeon those who sit in darkness.
8 “I am the Lord; that is my name!
I will not yield my glory to another
or my praise to idols.
9 See, the former things have taken place,
and new things I declare;
before they spring into being
I announce them to you.”
Psalm 2:7 I will proclaim the Lord’s decree:
He said to me, “You are my son;
today I have become your father.
8 Ask me,
and I will make the nations your inheritance,
the ends of the earth your possession.
9 You will break them with a rod of iron;
you will dash them to pieces like pottery.”
10 Therefore, you kings, be wise;
be warned, you rulers of the earth.
11 Serve the Lord with fear
and celebrate his rule with trembling.
12 Kiss his son, or he will be angry
and your way will lead to your destruction,
for his wrath can flare up in a moment.
Blessed are all who take refuge in him.
Genesis 49:10
The scepter shall not depart from Judah, nor the ruler's staff from between his feet, until tribute comes to him; and to him shall be the obedience of the peoples.
Isa 2:2 In the last days
the mountain of the Lord’s temple will be established
as the highest of the mountains;
it will be exalted above the hills,
and all nations will stream to it.
3
And many peoples will come and say: “Come, let us go up to the mountain of the LORD, to the house of the God of Jacob. He will teach us His ways so that we may walk in His paths.” For the law will go forth from Zion, and the word of the LORD from Jerusalem.
Isa 49:5 And now says the LORD, who formed Me from the womb to be His Servant, to bring Jacob back to Him, that Israel might be gathered to Him—for I am honored in the sight of the LORD, and My God is My strength— 6
He says: “It is not enough for You to be My Servant, to raise up the tribes of Jacob, and to restore the protected ones of Israel. I will also make You a light for the nations, to bring My salvation to the ends of the earth.”
Psalm 118: 22The stone the builders rejected
has become the cornerstone;
