The angel of the Lord also said to her: "You are now with child and you will have a son. You shall name him Ishmael, for the Lord has heard of your misery. He will be a wild donkey of a man; his hand will be against everyone and everyone's hand against him, and he will live in hostility toward all his brothers." (Genesis 16:11-12)There has been a lot of news recently about the protests in Iran and the violent put down led by the Islamic leadership, the mullahs. It got me to thinking about Islam in today's world.
Often we hear people say that Christians, Jews and Muslims all are children of Abraham and worship the same God.
The source document for Christians is the Bible. We share the first five books of the Bible (Genesis, Exodus, Leviticus, Numbers, and Deuteronomy) with the Jews. They call these books the Torah. We also share in a similar way the other books of what we call the Old Testament.
There is no question Christianity has it's source from the Jews. Jesus was a Jew and believed all that the scriptures said which, in his time on earth, was the Old Testament.
The main difference I see between Christians and orthodox Jews is we believe Jesus is the Messiah and the orthodox Jews do not. They don't accept Jesus as the Christ both as individuals and as a culture. However, I have never seen any evidence of any Jew saying that he/she had received a revelation from God that proves Jesus is just a man and was lying or crazy when he said what he said about himself and God.
I have no problems saying Christians and Jews worship the same God in heaven but we disagree on whether Jesus is the Messiah. Many Jews have come to that conclusion and they are still Jews. They worship in the traditional ways as their ancestors, but they believe in Christ as the Son of God, the Messiah.
However, it's different when it comes to Islam and Christianity.
Several years ago I did a presentation at our church in Ohio comparing what the Bible said about Christianity to what the Qur'an said about Islam. To prepare for that presentation I read through the Qur'an from cover to cover. It was a challenging read. I don't pretend to be an expert on Islam, but here are some of my perceptions from what I read.
Most of the Qur'an's writings are revelations supposedly from the Angel Gabriel to Mohammed. There are several stories in the Qur'an that come from the Bible (e.g., Adam, Noah, Daniel, Moses, etc.
Mohammed received his revelations over a period in the 7th century. Early in his life he tried to win converts to his new religion with little success. So for the rest of his life he spread Islam through military conquest. After his death Islam continued to spread through conquest until the 1600's. Besides the Middle East, Islam had conquered significant portions of Europe and large portions of Northern Africa.
One of the major differences between the Bible and the Qur'an is Jesus. As a Christian I acknowledge Jesus as the Son of God and that God is 'one in three' - God the Father, God the Son and God the Holy Spirit.
Islam sees Jesus as just one more prophet in a line of prophets (e.g., Adam, Abraham, Moses, etc.) that culminated in the prophet Mohammed. According to Islamic belief, the same revelation that was given to Mohammed was given to the earlier prophets, including Jesus, but it was corrupted by man. However, the revelation is final and complete in the revelation given to Mohammed.
They also deny Jesus's death on the cross and his resurrection. This is a critical, basic tenet of the Christian faith.
This is different from the Jews who have not accepted Christ as the Messiah. That's an individual and cultural belief. It is not written into their doctrines. Islam has made this a doctrine. Their belief that Jesus is not God is supposedly a revelation from Allah and it would be heresy (punishable by death in some countries) to believe otherwise.
After Mohammed died a collection of his sayings was compiled over the years into the Haddith and a lot of Islamic behaviors come from the Haddith - ceremonial washing, daily prayers, etc., - and a lot of these rules are combined into Islamic law called Shari'a. It is this law that requires women to hide their appearances by wearing burqas.
The word Islam literally means surrender or submission. For a non-Muslim, the Qur'an lays out three options: (1) convert to Islam, (2) live in dhimmitude, or (3) die. Dhimmitude is a subservient, second-class life under Shari'a law and requires a tax be paid.

Many people call Islam a religion of peace. From my reading, this is true - if you're a Muslim. However, non-Muslims, infidels, are to be conquered for conversion, dhimmitude, or death. Not much peace there.
The reason I'm speaking out about this today is I believe Islam is again on a campaign of conquest. It may be extremists of their faith who are pushing this, but I also see a lot of support in what is often called the 'main street.' After 9/11 there was much rejoicing in the street in most if not all Islamic cities.
This conquest is being attempted in different ways, including taking over a culture through assimilation. Shari'a law is now accepted in several European cultures. Islam's culture is never meant to be assimilated into the host culture, but the other way around - the host culture is to assimilate into Islamic culture.
To this day, the West, especially the US, is still called 'The Great Satan.' This is ironic to me as so many American lives have been lost helping Muslims - in Somalia, in Kosovo, and in Kuwait.
Supposedly Allah told Mohammed through Gabriel that Jesus is just a man. He is just another prophet whose words have been corrupted by infidels. If Allah also supposedly revealted the 'truth' that Jesus did not die on the cross, nor rose from the grave, then I cannot reconcile that god, Allah, with the God of the Bible whom I try my best to serve.
As I said before, I don't pretend to know everything about Judaism or Islam. The fact is, I know very little, but I'm still learning and I'm open to correction.
At the end of the day, I believe Islam is a false faith based on a false god. Allah is not the same God that Christians and Jews worship. Jesus is not just a prophet, he is the Son of God, who died on the cross for my sins.
