What are you talking about, they believe in the old testamebt, their God is the God of Abraham and the name of Allah is just a different translation, which mean God.
The koran was writting after the old testament just like the new testament was writting after the old testament.
Im not supporting islam, but thats the truth.
Christianity came after Judaism
Islam came after Judaism
Same thing.
What do you mean different attributes?
Luis, you are trying to preach us the muslim approach, but we (christians) never accepted it.
Our christian God is Trinity. An Only Divine Deity with three personalities = God Father, God Son and God Holy Spirit.
Since we trust that the personality of Jesus Christ (His mind) was the same with God Son, we also confess Jesus as a God.
Mohhamad proclaimed Allah to be God of Abraham and himself as a prophet.
But we, christians never agree with both claim.
From our point of view:
1) God is Trinity
2) Mohhamad is not a prophed, at all.
3) Quaran is lie, and a book inspired by Devil.
4) Alllah (after belonging to Islam) is a name of false = non-existed God invented by Mohhamad in co-operation with fallen angels.
Besides those, please take into consideration that Christianity strictly teach to curse every one who try to preach christians idea that Jesus was not crusified (apostol Paul wrote it directly).
Since Mohhamed and his followers - muslims, claim that Jesus was not crusified, we curse you, and never agree with whole islamic approach.
You started the senseles argument. We never agree to accept Allah (explained in Quaran) as same God with our Holy Trinity.
The Doomsday will show you (and everyone) whose approach is right and whose God is real and whose book is falsefull.
