Its hard to wrap your mind around, l know...but then again, we're only made to perceive 3 so its understandable lol we can only see lower dimensions, not upper (from a scientific standpoint anyway)
The 5th dimension, would be where "god" would reside. Try this...
Get a piece of paper. Now draw a stick man, with two stick men beside him. Now draw a circle around the man in the middle. This circle, as far as the stick man is concerned, is his jail. On his 2 dimensional plane, theres north, south, east, and west...he has no concept of "up". But you, in the higher dimension, you see this in its entirety; so all you would have to do is pick the stick man "up" off the paper, move him over, and set him back into his reality. To you, this was childs play, but to the stick men, their friend had disappeared into the next dimension, and reappeared outside of his cell magically. To the lower 2D beings, you are "god". Make any more sense?
