Biblical Concept: Multidimensional God
Introduction: God is, governs, or created the following Dimensions
Length + Omnipresence = 2 dimensions = visible length and God Who created it
Width + Omnipotence = 2 dimensions = visible width and God Who created it
Height + Omniscience = 2 dimensions = visible height and God Who created it
Time + Immortality = 2 dimensions = countable time and God Who created it
Spirit (angels and humanity) + Spirit God = 2 dimensions = spirit creatures and the God Who created them
Light of Angels, their natural spiritually visible dimensional form = 1 dimension
The dwelling light of God - His actual spiritually visible dimensional visage = 1 dimension
Heaven - God is a dwelling light Spirit. Heaven is a spirit place outside the visible universe = 1 spiritually dimensional volume
Triunity - Inside the actual spiritual light visage of God is an interplay of three Persons = 1 spiritually dimensional volume See Revelation 4:5.
Conclusions: God is Himself dimensionally: immortal, omnipresent, omniscient, omnipotent, heavenly dwelling, light, Spirit, Triunity. He is the Creator of 6 lower dimensions (length, width, height, time, spirit, Angelic light) + His 8 personally related dimensions (immortal, omnipresent, omniscient, omnipotent, heavenly dwelling, light, Spirit, Triunity) = a minimum of 14 operational dimensions for the God of the Bible.

Isaiah 66:22 "For just as the new heavens and the new earth Which I make will endure before Me," declares the LORD, "So your offspring and your name will endure.
 NAS Romans 1:20 For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. Creation tells us about God. The dimensions of length, height, width, and time demonstrate that God has dimensional mastery over these realms as Creator. Also, God and the angels He created, have a light visage which suggests spiritual dimensionality—a spiritual volume. The third heaven, the dwelling place of God, is described as having a throne area (Revelation 4:1-4), suggesting a spiritual dimensional volume. The myriads of angels around the throne suggests an incomprehensible dimensional spiritual volume (Revelation 5:11). The slain humans of the tribulation period (Revelation 6:9), in their interim resurrection bodies (Revelation 6:10-11), suggests a heavenly spiritual dimensionality.
 It is interesting to note that physics string theory of today suggests a 10 dimensional universe at the initial instant of the creation event. String theory (subatomic waves of energy) searches for a unifying equation between the worlds of general relativity (Einstein’s theory of general relativity unified matter, energy, length, width, height, and time--the very large) and quantum mechanics (study of the subatomic structures of nature--the very small). String Theory, and its 10 dimensions, is able / trying to mathematically unify the physics of the very large and the very small.
