Not only that, but Peter died on a cross also. Now why would a follower of Jesus be willing to die on a cross for nothing?
Muslims believe that Christianity is a false religion. Of course, Muslims will respond by arguing that Christianity is a false religion because it was corrupted by man, but that in its original state it was the message of Allah given to Jesus the son of Mary.
If Islam is true, the existence of Christianity makes no sense at all. Why would God allow Jesus’ followers to believe He died on a cross? It would lead to the formation of Christianity, a supposedly false religion.
If Christianity is true, the rise of Islam makes perfect sense. If it isn’t immediately clear why Christianity entails the rise of religions such as Islam, consider the following line of thought.
If Christianity is true, then the following statements are also true:
[1] People can come to God only through Jesus Christ.
[2] Satan is a real spirit being who wants to keep people from God.
Satan, by definition, is an evil spirit who wants to keep people from God. Now, if Satan wants to keep people from God, and if the way to God is through Jesus Christ, what would Satan’s highest priority be? His main goal wouldn’t be to get people to lead immoral lives [though he would prefer that we do, since this corrupts God’s created order]; instead,
his primary aim would be to incite people to
reject Christ, for this rejection is what keeps them separated from God.
But how would Satan convince people to reject Christ? We should note here that there are plenty of people in the world who simply don’t care about God. Satan doesn’t have to worry about them, because they aren’t interested in salvation anyway. Since his goal is to keep as many people from God as possible, we would expect Satan to be more focused on people who are to some extent concerned with religious matters. There are two ways to keep such people from God. Satan would either have to convince them that all “religious talk” is nonsense * or he would have to offer them a substitute for the truth *.
Thus, if Christianity is true, we would expect Satan to inspire religions that reject Christ’s sacrificial death and resurrection, even though these religions may be similar to Christianity in other [non-essential] respects. Now that we have a clear picture of what we would predict if Christianity were true, let us see how Islam matches up with our prediction.
The message of Islam is something like this: “Believe in God. Do good deeds. If you do enough of them, you’ll get to heaven. Respect Jesus, for he was a mighty prophet, who delivered God’s message to the children of Israel. Also believe that Jesus was born of a virgin, that he performed many miracles, and that he was the Messiah. But whatever you do,
don’t believe that he died on the cross for your sins.** And
don’t believe that he rose from the dead. In fact,
the worst possible sin you can commit is to believe that Jesus is the Son of God.”
Notice that Islam rejects Christianity’s essential requirements for salvation while accepting certain other doctrines. For instance, Muslims are commanded to believe in God, but even Satan and his demons believe in God. Muslims are commanded to do good deeds, but all religions teach this. Muslims are allowed to believe certain things about Jesus [such as his prophet status and virgin birth], but these beliefs do not
save a person. Yet when we come to beliefs that are essential for salvation – the deity of Christ, his death on the cross, and his resurrection from the dead – we find that Islam is violently opposed to these crucial doctrines. Islam, then, looks exactly like the religion we predicted that Satan would form, for it denies what is necessary for people to come to God.
