Allah is arabic for The God. Its not my god vs. your god. When we say omG, we r all referring to the same God, whether we like it or not. God is one and the same, known by the best names, and closer to us than our own jugular vein.
Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? Qur'an: al-Anbya' (The Prophets) 30
