No one can say that yes, Islam is the correct religion or Christianity. This a matter of faith, and for me, I see that Islam is the most logical religion among all religions. For example, how can God have a son and this son is human? Does this mean that God is human? How is that, and God is the one who created people with his own hand? (God is something that no one can imagine because it is beyond logic and science because our mind can't comprehend it)
It's just my point of view and I hope no one acts like a child and starts swearing at me or something.
