Why do you invent all this nonsense instead of simply reading the Koran and realizing it is true?
Islam states that Christians and Jews, People of the Book, are believers. The Koran address the subject of comparative religion and why we are different religions. The Koran confirms the Torah and the Gospel.
Islam is perfect, it addresses every theological loose end and perfects religion. Christians and Jews debate for centuries, inventing doctrines and condemning each other to Hell, Islam settles this.
The Koran and Sunnah, the Shariah, are the perfect guidance for humanity and government. Every worldly ideology pales in comparison to God's command for humanity.
Islam will soon be the largest religion in the world, in a matter of decades after over 1,400 years. Will you read the Koran then? How long can you ignore Islam? God sent a Prophet, salallahu alayhi wa salam, and it is wise to obey God and submit to God.
