I never refer to myself as an Israelite but a heir of the promises of Abraham through his seed (one person) The Lord Jesus Christ. I am white Caucasian and I hate multiculturalism.

Below the scriptures are clear that belief come from the hearing of the gospel, with believing come baptism (immersion) which post John the Baptist is always speaking of immersion of the Spirit. Verse 28 Iewe means Judahite here while Greek means nations. Salvation isn't exclusive to the Israelites. It's for anyone called by the gospel and led to saving grace by God.

Galatians 3:16,18-19,22,26-29

[16]Now to Abraham and his seede were the promises made. He saith not, And to seeds, as of many, but as of one, And to thy seed, which is Christ.

[18]For if the inheritance bee of the Law, it is no more of promise: but God gaue it to Abraham by promise.

[19]Wherefore then serueth the Law? it was added because of transgressions, till the seed should come, to whome the promise was made, and it was ordeyned by Angels in the hand of a Mediatour.

[22]But the Scripture hath concluded all vnder sinne, that the promise by faith of Iesus Christ might be giuen to them that beleeue.

[26]For ye are all the children of God by faith in Christ Iesus.

[27]For as many of you as haue bene baptized into Christ, haue put on Christ.

[28]There is neither Iewe, nor Greeke, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Iesus.

[29]And if yee be Christs, then are ye Abrahams seed, and heires according to the promise.
