do christians know they cant debate with Muslims on religion ?

I'm quite certain that no one knows that.

You'll note that I have just now debated with a Muslim on religion and failed to convert to Islam as a result.

I know several Christians who were formerly Muslims. In my more than 25 years as a Christian, I don't know anyone who has claimed to be a devout Christian who has subsequently converted to Islam. So your claim is inconsistent with my experience and observation.

If you had such a strong, unequivocal argument, you would have led with that rather than empty, unsupported assertions.

I have no desire to debate a muslim or anyone else about religion. I concentrate on my personal relationship with God. He is my Creator and Savior. I spread the "Good News" to anyone who expresses an interest and also through my example of living a Christian life.

You're just as gullible, delusional, and pathetically indoctrinated as any other theist, regardless of the religion. Your head has been filled with lies, and you're too desperately naive to realize it.

You might believe such a claim, but it is not so. As Rufus has stated, such a few individuals who may embrace what Islam claims, were nebulous in the first place in their personal philosophy and theology.

i highly doudt that....why join a cult?.....any religion that makes you pry 5 times a day is a cult....god can see into every humans heart..so god does not need the over worship they make muslims do..

Of course; as a rule Christians can't successfully debate anyone on religion. Not much of a challenge there; Muslims as a rule can't either unless they're debating Christians. Do you get points for it somewhere?

Yes, of course, they all become Christians so no debate.

There's many Christian and Muslims apologists who have debated each other.

Believers seldom change their faith.

I guarantee you will not be able to convert a single Christian here.
