Rom 11:17-18
17And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree;
18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
We gentile believers should not boast about our being grafted into Covenant Israel [ the election of grace], for it was not because we were better than they, or more in tune with God than they, but simply because we were blessed to be Chosen in Christ too before the foundation of the world, we were also, foreknown of God. Rom 11:2;Rom 8:29
Acts 15:13-18
13And after they had held their peace, James answered, saying, Men and brethren, hearken unto me:
14Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name. What Name ? See
2 Sam 7:26;
1Kings 8:17,
20;
Ps 76:1;
Isa 48:2
15And to this agree the words of the prophets; as it is written,
16After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:
17That the residue of men might seek after the Lord, and all the Gentiles,
upon whom my name is called, saith the Lord, who doeth all these things.
18
Known unto God are all his works from the beginning of the world.
It is because we were chosen in the root [Jesus Christ] that this privilege comes to us gentiles !
In
Acts 15:16 above,
the tabernacle of David is being equated to the calling in of the elect gentiles, this again confirms the oneness of the People of God and the Covenant Israel being comprised of both jews and gentiles who were Chosen in the root, Jesus christ before the foundation of the world.
