The Christian context of using Allah is not the same as the Muslim's context of using it. For Christians they just use it as a title for God as used by Arab Christians for hundreds of years and also by the East Malaysians even before the formation of Malaysia.  It is not used by ALL Christians in Malaysia but just those from the  East Malaysia who are Malay speaking or those who use BM exclusively like the Orang Asli. The reason Malay speaking Christians use Allah just as a title and not as a personal name for God because the God of the Bible already has a personal name - Yahweh. That is His name forever as is written in Exodus 3:15 which means the great I AM. That is His personal name. This Yahweh has NOTHING to do with the Allah of the Koran. Allah is not a title but the personal name of the god of the Koran which incidentally pre-existed Islam. There are too many theological differences between the God of the Bible and the god of the Koran. For starters the God of the Bible loves the Jews and the nation of Israel but the god of the Koran does not. The God of the Bible has a Son and the god of the Koran does not. The God of the Bible is a Father to the nation of Israel and to all people in general but the god of the Koran is a father to none. The highest relationship between a Muslim and Allah is that of a Master - Slave.

Christians know that when they call their God in the BM language they are only referring to the God of the Bible only and NEVER to the Allah of the Koran. They only use the word as a title and not as a personal name.
