Which group of "believers" is deceived, Christians or Muslims?

My mother shared with me last night her Pastor recently invited and hosted a group of Muslims (his new friends) in a town hall setting at their church to speak to their congregation to learn more about Islam, as sort of a "look, no need to fear these people, they are kind and sincere loving people". "ask them a question"

...My mother was ticked off about the whole thing, asking her pastor "are you invited to go speak to their congregation, probably not right?"...I laughed and told her it was a good thing to learn and have dialogue with all people!!!.... and she should re-consider attending the next gathering and ask her questions...("Would Christ turn down that invitation?")

With that said, If you had a small group of Muslims speaking to your church offering friendship via your pastor, many thoughts are crossing people's minds, many of which they probably wouldn't want to confess in a public forum.

For me, I would ask the following:

To my fellow Christians, "do you believed Muslims are deceived? Yes or no? Please support your conclusion with scripture." (bible)

If you believe Muslims are deceived, "do you feel compelled to share about Christ? If you do not, what is holding you back?"

To the Muslims, "do you believe Christians are deceived? Yes or no? Please support your conclusion with scripture" (Quran)

"If you believe Christians are deceived, do you feel compelled to share your faith to Christians about Islam? If not, what is holding you back?"

Can you imagine the responses you might hear?

Why are these questions important?

The conflict between Christians and Muslims is well documented for centuries and there is a new movement in America to mock all religions with an attitude "they're all deceived and wasting their time".

Apathy towards religions changes nothing, ignorance and fear is not bliss.

Your thoughts?
