Duh... Thus the reason for evangelization, which is Warren's context.
The presumption I've mostly see expressed here on the board so far is that it is simply better to leave all those millions of people to die in their sin because we disagree with them and because they have a perverted book that doesn't portray accurately all that the Bible of Christains does.
What a silly notion, and what a SINFUL notion, all because a counterfeit book leads people astray from the one true God of Abraham, Isaac, and Joseph.
The larger point here, Warren aside, is that the "concept" of "Allah" remains the same for the God of the Bible or for the god of the Koran. As the Koran is nothing more than a perversion of the Scriptures of Judeo-Christian origin, they "might" be used to instill the very basic concepts of God into Muslim adherents, for they -- like many (or even most) in Christendom -- do not understand their own scriptures but rather follow religious leaders and teachers who may also not understand their own religious writings. A careful apologist for Christianity can present many tenets of pure Christian doctrine FROM the Koran which can, under the leadership of the Holy Spirit, cause the Muslim listener to investigate further the claims of the true Scriptures.
Since you posted this to me, I have to ask..huh?
I never implied Muslims shouldn't be witnessed to. I was pointing out to Crab that Islam teaches a different gospel since he was trying to so hard to compare it to our true faith. I didn't mean to ruffle your feathers.
