Allah is a false god. He is not the God of the Bible. If he is anything, he is a demon or even Satan himself.
The lady was right in what she did, boldly proclaiming Jesus Christ as the only Way to salvation. The time for “politeness” in the face of evil not only is long gone, but never really was.
So do you think our Arabic-speaking brothers should abandon the word for “God” in Arabic to Muslims, when they had used it for some centuries before Islam existed?
BTW, in Arabic Bibles, the Hebrew, Greek and Aramaic words for God are all translated as Allah.
As for whether her methods were appropriate or not, I can’t help thinking of all those incidents in the New Testament where Jesus Christ and his apostles boldly disrupted pagan religious services to proclaim Jesus Christ as savior.
Ohh, wait...
AMEN.
