Yes, you got me,
Islamic Allah is not the Christian's God(JEHOVAH)

Many people (especially Christians) even pastors and general overseers make the mistake of referring to Allah as God,

Hey, look am not trying to claim all wisdom but we all learn everyday, maybe you or your pastor doesn't know, so the fact that he makes use of it, doesn't make him perfect, he is wrong and you can correct him.

First of all, I am a Christian.
The way some Muslim act towards us, the Christians, made me doubt if Allah is JEHOVAH. For this reason I took extra studies and researches, read both Islamic and Christian books, to see the similarities between these two deity but unfortunately after much reading of the Quran and discussion with a Muslim colleague, i discovered that Allah isn't JEHOVAH.

A God whose son is not Jesus Christ is not JEHOVAH (1 John 5:5, 1 John 5:20).

The Quran clearly says Allah has no son(sura 23:91, sura 72:3, sura 43:15) contrary to what John 3:16 says.

May God increase our knowledge and make us know him more in truth and in spirit. AMEN.
