“It all depends on why these Muslims are associating with Christians. Are they looking for a deeper understanding of Jesus? Or are they cynically looking for allies against the Jews?”
I’d say it depends on the shepherd who is leading the flock over there. Pray for that church. Pray also that the Holy Spirit comes down upon these Muslims.
Look we got them in our churches, that is a start. Let the Spirit work on them. Keep praying and the Lord will work in His time.
Islam specifically denied the Deity of Jesus Christ.
It is impossible to remain Muslim and be a Saved Disciple of Jesus Christ (hope that answers your question).
Obviously that’s the objective.
But I doubt that many will truly walk away from Islam.
