Everything that causes us to be 'the 3rd Dimension'. God doesen't exist in the 4th dimension. God doesen't exist in any dimension. God doesen't exist at all. That's the definition of Faith in the Bible.
Time is certianly part of it.
It's a theme that has permeated the consiousness of humans since 'time began'. We are subject to the laws of this universe' period. Everything that causes us to be 'the 3rd Dimension'. God doesen't exist in the 4th dimension. God doesen't exist in any dimension.
