Unlike Americans or Western countries that have familiarity with Christianity as it is, Muslims are taught Christianity is the enemy of Islam.
Therefore a simple presentation of the Gospel message, and they're acceptance of Jesus is often times, more than not, in order to be “accepted” in this country ...is not sufficient to assume a conversion has occurred.....as even overseas many are being baptized as Catholic in order to claim asylum as being persecuted for their faith.
Part of the Islamic Stealth Jihad is to infiltrate Christian churches....and these people are seasoned liars as they've had to do so to survive just daily in their volatile country even as a practicing muslim.. Jesus called the church, his church to "Go out" with the Gospel Message.....I think it more than wise and necessary to be very cautious of Muslims who come into the church....it takes months and months for them to grasp the Gospel message and it's full meaning.....there's a degree of deprogramming that also comes into play. And I would add only those who are well versed in scripture should take on instructing a Muslim.....they often times believe these conversations are to convert the person teaching them.
And I wouldn’t disagree with what you’ve written. But does it ever stop us from reaching out - whatever that means in each context? You can never discount the Holy Spirit - not saying that you have - being at work in their lives. Granted, it certainly takes a wise as serpents and harmless as doves approach to reaching out, but you can certainly see the opportunities we have before us. It’s just so complex.
