a lot of folks know this, and think it ends at isaac and ishmael and the split after abraham's generation. the depth of crossover is much deeper, and it would serve islam well from a PR standpoint to talk about it more.
In Islam, Jesus holds roughly and equivalent spot to which John the Baptist Holds in Chrisianity.
In Islam, Jesus was the great prophet prior to the final prophet, Muhammed.
In Islam, Jesus was born of a virigin birth.
In Islam, Jesus was even as a child, pure and without sin.
Muslims believe that Jesus ascended to Heaven, although typically reject that he was crucified, died and absolutely reject that he rose.
Muslims believe that Jesus will return for the day of judgement to defeat the antichrist.
The facts you post here may be true to a degree.....so what? The Mormon and Jehovah's Witnesses likewise believe variant aspects of what you deem as "crossover" to the Biblical narratives....do similarities make those faiths valid or desirable? Or do the similar aspects found in fact reveal something else?
In Islam, that "equivalent spot" stands in stark contrast to the Jesus of the Bible who described Himself as "the way, the truth, and the life"....and of whom John the Baptist said he wasn't worthy of untying the laces of His shoes.
The Biblical Jesus said that he came to fulfill all that was spoken of Him in the Law and by the prophets, and any who came in the future claiming otherwise would be FALSE prophets( ahem, Muhammed, Joseph Smith, et.al.).
The Bible says "all have sinned and come short of the glory of God", yet clearly states Jesus was sinless and therefore God incarnate. Nevertheless, the Islamic faith rejects the Jesus of the Bible and elevates a murderous pedophile above Him.
What good are similarities when those similarities are designed to deceive people and keep them ignorant or blind concerning the truth? The God of the Bible hates a mixture. The Israelites were forbidden to have garments made of both wool and flax. Why? A little leaven(representing sin, or doctrinal error) corrupted the whole loaf.
The Bible claims that there is a deceiver who is a MASTER at mixing truth and error. My point? The fact that Islam agrees in parts to some of what the Bible teaches should not be heralded as a "service to Islam's PR problems". Rather, it should be seen for what it is: a counterfeit of the True God, the True Scripture, and the True Faith. Remember, there's always real cheese in a rat trap.
