But what is it about Replacement Theology that blind so many adherents to the goals of the Muslim World?
I don't know what you mean about "Replacement Theology" so its hard to understand your question. The only folks who best describe a "replacement" theology are the Dispensationalists who replace the Scriptural teachings concerning the LORD's Church with a secular state made up of a majority of ethnic Jews; Futurists also replace the Doctrines of Redemption with recapitulation into a perpetual blood sacrifice system; Dispies also "replace" the focus on Christ and His Church with the Antichrist and his minions.
That is the sort of "replacement theology" I see going on. And I already know that you feel that the Muslims are going to conquer
They want to Islamicize the world.
And the Roman Catholics, and the non-Premillennialists want to Christianize the world while you Dysfunctionalists wimper in the corner wailing "Woe is me".
At best your descendants would be Dhimmi.
That statement makes no sense. If Futurism is real, then allegedly those with Faith in Christ will be removed before that takes place. Since Futurism is not real, its business as usual:
Genesis 16:12"And he will be a wild man; his hand will be against every man, and every man's hand against him; and he shall dwell in the presence of all his brethren."
Christianity survived the Crusades, the various Caliphates and the Ottoman Empire. You really believe deranged, illiterate and impoverished 3rd Worlders who embrace a 6th century technology and lifestyle and worship a moon god can really overtake modern civilization and the True God? Talk about rooting for the underdog. (sigh)
Their weapons are rocks, rape, shouting and a high birthrate. Given what is happening in Africa, the Christians have taken the birthrate weapon away as their children come to Faith in Jesus Christ. I think I have enough stuff in my arsenal to deal with rock throwing, rape and shouting. We are not alone.
