Well, as always the question is answered differently by different deists but this is one there is largely a consensus on. Most deists would say, indeed there is “one creator”, one supreme intelligence but many different views of that exist. Again I can only give you my view.
I would define God as a singularity. I personally define God sum total of all consciousness and intelligence that exists in the entirety of all space, matter, time and dimension. Some would call this pantheism, most of those that do so with any negativity are followers of one of the revealed religions.
Pantheism is simply defined as, “the view that everything is part of an all-encompassing immanent God,or that the universe, nature, god and divinity are all identical.” A lot of evangelical pastors get their panties in a wad over pantheism stating that it basically says that everything is god, hence man is god. This is simply typical defensive religion, acting out when anything challenges their view of faith.
Frankly pantheism is a far more inclusive view of what Christians call “the body of Christ”. To say that we and everything else that exists is a part of God is not to say that we are all God, that is just nonsense. That would be like saying since your big toe on your left foot is part of you, your toe is you. Cut off your toe and you still exist, incinerate it, compost it or feed it to a dog and you still exist do you not? Yet while attached to you it is part of you right? If you stub it you feel pain, if it is tickled you laugh, if you get a foot rub you feel pleasure or if you get bit by an ant on it you itch.
This is why I choose to use my reason to see God as a singularity. I believe that you and I and my dog and all energy and consciousness are part of God, yet that singularity exists in a single point as well. In fact reason would lead us to believe that this is the only way God could be omnipotent and omnipresent. For God to know you as well as you know yourself God would have to be part of you, see though your eyes and understand the world and the universe as it exists in your heart.
Think about it this way, the creator cannot be omnipresent if God only sees the universe or more accurately the multiverses as they exist for God. God must know how all things exist for all beings. This is how I view God, a singularity of all consciousness and intelligence that is connected to the same.
