This passage comes to mind when considering islam:
34 But a Pharisee in the council named Gamali-el, a teacher of the law, held in honor by all the people, stood up and ordered the men to be put outside for a while.
35 And he said to them, “Men of Israel, take care what you do with these men.
36 For before these days Theudas arose, giving himself out to be somebody, and a number of men, about four hundred, joined him; but he was slain and all who followed him were dispersed and came to nothing.
37 After him Judas the Galilean arose in the days of the census and drew away some of the people after him; he also perished, and all who followed him were scattered.
38 So in the present case I tell you, keep away from these men and let them alone; for if this plan or this undertaking is of men, it will fail;
39 but if it is of God, you will not be able to overthrow them. You might even be found opposing God!”
It makes me wonder why islam has lasted so long. What came to me is that the men spoken of in the passage were Jewish and claiming to be great or the messiah or some such, whereas islam was invented by someone totally unrelated to the people of the Old or New Covenants. It is a different religion altogether. A number of Far Eastern religions began B.C. and still exist. Again, they are totally unrelated to God’s covenants. Do you think we will always be stuck with islam and its violence? Do you think the number of muslims will dwindle and no longer be a great threat to the safety of Christians or no longer be a threat to peace?
