Christians need to wake up to the fact that according to the Qur'an and Hadith, Islam teaches that Christianity is corrupt and must be eliminated.

Contrary to what most Christians think, the Muslim "Jesus," Isa, which must appear according to Islam, is a Muslim! Furthermore, the Qur'an itself says that Jesus and his disciples were Muslims (Sura 3:52, 4:171-172, 5:111-112, 5:115-117). Therefore, according to Islam, when Isa comes, he will come as a devout Muslim. Sura 4 denies Isa's divinity and Isa is coming to correct the "errors" of Christianity as a sort of enforcer for the Mahdi.

If Allah is really Jehovah, then reading the Qur'an and the Bible proves only that God is schizophrenic. How much clearer does it have to be? Islam serves a "different Jesus," has a "different god," and spreads a "different gospel"  Eric Barger/Take a Stand
