Replacement theology is indeed a lie which can be supported by neither Scripture nor history.
God's plan for His chosen people Israel is right on track, starting in modern times with His bringing His people back from around the world into their land which He gave them, the fulfillment of prophecy on May 14, 1948 when the nation of Israel was born in one day (the only nation in the history of the world to be reborn after 2000 years of nonexistence and to be reestablished in one day, just like God told us it would), the fact that, just like God said, the birth of Israel came before the labor pangs, and, in our own lifetime, the fulfillment of Zechariah 12:3.
A belief in replacement theology results from spiritual blindness. Those who have bought into it are, inexplicably, especially resistant to Biblical truth about the fact that God has not thrown away His chosen people, He has a plan for them which includes an exalted position for them during His millennial kingdom, He states clearly that the day will come when all Israel will be saved, and we are witnessing His plan for His people being carried out.
As you know I'm against all forms of "replacement theology."
By all "all forms" I mean those beliefs which foster hatred toward the natural branches (supremacism > Holocaust) - to the more benign beliefs that boast against the natural branches.
It is all outside the will of God:
Thou wilt say then, The branches were broken off, that I might be graffed in.
Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: For if God spared not the natural branches, [take heed] lest he also spare not thee.
Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in [his] goodness: otherwise thou also shalt be cut off.
And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural [branches], be graffed into their own olive tree?
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: For this [is] my covenant unto them, when I shall take away their sins.
As concerning the gospel, [they are] enemies for your sakes: but as touching the election, [they are] beloved for the fathers' sakes.
For the gifts and calling of God [are] without repentance. - Romans 11:18-29
