The God of the Bible is one God, unlimitless in power. He manifests himself to us in more than one way, in more than one form. He can be in a million places at once, and still be almighty. He created all things and through Him they are held together. This is my God.
The Trinity is one way this is explained, but He is so much more than our understanding. He is inside me. There are those identified as Christians that do not yet have His Spirit inside of them, teaching them all things, and there are Christians such as myself that don't have a perfect understanding, for as the scripture says, the way we see God now is as if in a smokey mirror. We have not reached that which is perfect.
In Christ,
