Abraham was told his descendants would be in number like the grains of sand by the sea, and nothing more.
He was told his descendants would be in number like the stars in the heavens.
Interesting, the devil in Isaiah 14 said he will elevate himself above the stars of God... and in Revelation 13 his messiah will rise up from the sand by the seashore.
Revelation 13:5-10 (NASB95)
5 There was given to him a mouth speaking arrogant words and blasphemies, and authority to act for forty-two months was given to him.
6 And he opened his mouth in blasphemies against God, to blaspheme His name and His tabernacle, that is, those who dwell in heaven.
7 It was also given to him to make war with the saints and to overcome them, and authority over every tribe and people and tongue and nation was given to him.
8 All who dwell on the earth will worship him, everyone whose name has not been written from the foundation of the world in the book of life of the Lamb who has been slain.
9 If anyone has an ear, let him hear.
10 If anyone is destined for captivity, to captivity he goes; if anyone kills with the sword, with the sword he must be killed. Here is the perseverance and the faith of the saints.
Zechariah 8:23 (NASB95)
23 “Thus says the Lord of hosts, ‘In those days ten men from all the nations will grasp the garment of a Jew, saying, “Let us go with you, for we have heard that God is with you.” ’ ”
Revelation 17:12 (NASB95)
12 “The ten horns which you saw are ten kings who have not yet received a kingdom, but they receive authority as kings with the beast for one hour.
The Church is in a major identity crisis because most refuse to believe the Church is Spirit Israel (always was even before Gentiles were grafted in).
Romans 9:6 (NASB95)
6 But it is not as though the word of God has failed. For they are not all Israel who are descended from Israel;
Romans 2:28-29 (NASB95)
28 For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh.
29 But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God.
Romans 11:16-26 (NASB95)
16 If the first piece of dough is holy, the lump is also; and if the root is holy, the branches are too.
17 But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree,
18 do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you.
19 You will say then, “Branches were broken off so that I might be grafted in.”
20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear;
21 for if God did not spare the natural branches, He will not spare you, either.
22 Behold then the kindness and severity of God; to those who fell, severity, but to you, God’s kindness, if you continue in His kindness; otherwise you also will be cut off.
23 And they also, if they do not continue in their unbelief, will be grafted in, for God is able to graft them in again.
24 For if you were cut off from what is by nature a wild olive tree, and were grafted contrary to nature into a cultivated olive tree, how much more will these who are the natural branches be grafted into their own olive tree?
25 For I do not want you, brethren, to be uninformed of this mystery—so that you will not be wise in your own estimation—that a partial hardening has happened to Israel until the fullness of the Gentiles has come in;
26 and so all Israel will be saved; just as it is written, “The Deliverer will come from Zion, He will remove ungodliness from Jacob.”
To hear most tell it, God abandoned the natural branches and started a new tree called the Church.
Galatians 6:13-16 (NASB95)
13 For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised so that they may boast in your flesh.
14 But may it never be that I would boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.
15 For neither is circumcision anything, nor uncircumcision, but a new creation.
16 And those who will walk by this rule, peace and mercy be upon them, and upon the Israel of God.
