So you're not eevn sure who this Spirit is?
Didn't the Quran reveal what the Spirit is?
The prophets said He was the very Spirit of the LORD.
If Islam doesn't confirm that, it's wrong.
Technically, I really don't care what in the world the Spirit is. I worship my Creator and ONLY my Creator, and that is good enough for me. Some say it is God's Spirit, some say it is Gabriel. I think they mean Gabriel but thats just me.
