The Christian God is also from two other religions, but it's Jesus' teachings in particular that appeal to me. Admittedly those teachings could be equally valid without him being the son of God or the Messiah, but there are several angles from which Christianity does make more sense to me than other religions. Though I admit my knowledge about most other religions is much more superficial.
I'm sure it also matters that I was raised a Christian, but my faith now is not exactly the same as it was when I was young. It went through a lot of phases before ending up like this.
