Bible predicts the coming of the Prophet Muhammad
I will raise up a prophet like you from among Their brothers. And I will put my words in his mouth, And he shall speak to them all that I command him. Deuteronomy 18:18
The Prophet what this verse is about is of course Moses. Who are the brethren of Moses? Let us follow the bloodline, then we come to visit Abraham, who had two sons, Isaac and Ishmael. The tribes of Israel are largely Isaac and the brother of Isaac was so Ismael, of Arab origin, an origin from which we can recognize the prophet.
And who is the prophet who most resembled Moses? Mohammed course.
And we also know that Muhammad could not read and write and that Gabriel's words in the mouth of God would explain that Muhammad was obliged to share with his followers.
Or if you give the scroll to someone who can not read, and say, "Read this, please," they will answer, "I do not know how to read." Isaiah 29:12
Again, clearly the Prophet Muhammad, to whom Gabriel said he could not read.
Any way, from your post I understood that you are Christian and I wanted to inform you that both scriptures (even current day version) prophecies of the coming of a Prophet among the Arab, even more even his name is mentioned and especially the most important events are described in details. Look for it and you will find that this Prophet can only be Mohammed (Peace be upon him).
About Islam is out of date, Islam is universal and it presents a complete way of life and it is up to you
