Some people say that Jews, Muslims and Christians believe in the one same God.
I don't agree with that.
Although these 3 religions are related, all of them believe in very
different Gods. Let me show you why below --
Christians - Most Christians believe in a Trinity God, that is Father, Son and Holy Ghost are all God. To Christians, Jesus is God and also part of the Trinity God.
Muslims - Muslims believe in one God but not in the Trinity sense. The name of the Muslim God is Allah and Muslims do not believe that Jesus was God.
Jews - Jews also believe in one God but the name of the Jewish God is YHWH. Jews define their God very differently from the Muslim defintion too.
3 very similar religions but yet all 3 believe in different Gods.
