If you were to ask such a question to the vast majority of Christians today, they would promptly respond that it is the political state of Israel created in 1948. In general, the average Christian would consider themselves to be the “church”, while separating Israel to a country in the middle east.
Though a doctrine called dispensationalism, there is a distinct separation between who the “church” is and who “Israel” is, and the majority are taught this within their congregations, and very few question it. Ever since the introduction of the Scofield Bible (1909), taught in seminaries nationwide, which separates church from Israel, not only has prophesy been manipulated, but it is quite an identity crisis, when all throughout Scripture the assembly of God, Israel, is always His people, a covenant people of God.
Gal 6:15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.16And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.
