I wouldn't bother, if I were you, with elaborate conceptions of God.
It might be helpful to stick just to this: God fills the universe and you and me, God is good, God's will is in everyone's best interests, and if you want to serve God and not self, He'll be happy to point you in the right direction and give you everything you need to be OK.
Anything more sophisticated than that, and you'll likely run into difficulties.
A lot of people tie themselves up in knots trying to come up with a conception of God they understand, discovering that it does not answer all the questions, then abandoning the effort to actually establish a relationship with God out of the cynicism that then develops.
I'm all for what a friend of mine once said: less thinking, and more believing.
