You seem to have done well with yours.
I apologize, maybe it would have been better to say "we have difficulty with our human dimensional brains"
If he created us, so do we.
Not quite, we live in a dimension governed by laws that do not confine God. Fish can be put in an aquarium inside your home. Do you live by the same confines as them? They are limited by length, width, depth, O2 levels, waste levels, food being supplied, other fish being added that may be aggressive or food.
You, in the mean time, can walk where you want, have unlimited O2, waste is handled, while the fish are dependant.
This is not a perfect comparison, however, I think it's easy to see that the creator can live outside the limitations of a realm of dimension that it has created.
And yet, if we truly are His creation, then we too are part of His dimension.
This "if, then" statement is correct to a point. We are a dimension, inside His dimension with far more limitations than His.
Consider the following:
Imagine that the larger bowl is God's dimension, and the smaller one -- the bowl inside the bowl -- is our own. The same rules that affect the larger bowl will affect the smaller one inside.
Can you really have God simultaneously having created our dimension and then hiding outside of it, claiming the rules don't apply to him?
Consider this, we are a small bowl floating an ocean. God's dimension is not limited in any way to ours. Ours was created by Him. Consider that you create a song, It is only in existence when some one sings or plays an instrument. The instrument is eternal in relation to the song. The song is only evidence when it is played. God is the writer of the song, and the instrument that plays it. We are infinitely miniscule in comparison and are at the whim God.
If our dimension is a bowl. God's is not just a bigger bowl.
