The bible says God is Spirit, spirit is often denoted as energy, and science now tells us that energy is immortal, with no beginning , or end.

Note : God = Not a name, but a description given to an entity that needs only itself to exist.

Spirit= Energy, breath, wind (solar energy), force, etc..

"God Is Spirit" -- John 4:24 [NKJV, NAS, NIV all translate this correctly, in the original Greek, it is written, "God is spirit, not God is a spirit".]

Notice, never does the bible say that God is a spirit , it says that God Is spirit. Now, spirit is energy, force, & wind. Therefore, one could say God is not merely an energy, force, wind.  God is energy, force, wind, because it is synonymous with spirit. - So, According to scripture, "God" Is infinite, and extant, based on the following scientific explanation:

First of all, the Laws of Conservation have been thoroughly tested to show that matter or 'energy' can be neither created or destroyed, the same amount of "energy" is always dynamic. A building could explode, and although it looks completely different, the same amount of energy would be subsisting within the universe.

In physics, the 'Conservation of Energy' also states that the total amount of energy remains constant, Even if it changes forms. The Law of Conservation states that energy cannot be created or destroyed. So, in regards to the universe, it is evident that the energy comprising the universe must have ALWAYS existed somewhere, and even though the universe obviously hasn't always looked the way it does now, the Law of Conservation says that energy is not minimized based upon a change in material formation. So, is it possible that the energy within the universe is eternal even without the universe being in the external appearance as it is now? By all means, for the First Law of Thermodynamics supports this as well.

So, the question becomes, originally, what was that energy that is, and was the universe, and where was its residence? Remember, if "God" Is spirit (energy), then a concept of universal energy at one point existing within Itself is not complex, right? By no means. Of course energy can exist within itself. Any other conclusion would be paradoxical. Even scripture says repeatedly that All things existed within God. It is absolutely intriguing how over 2000 years ago (New Testament) and over 4000 years ago (Old Testament), God was equated with energy, and attributed to being In all and containing all, and Now with today's apparatuses, science shows that energy is neither created or destroyed, and at one point even existed in a state of isolation.

Again, people get confused when they think the term "God" is a 'name' for some giant with a grey beard who lives on a cloud. The bible clearly so articulates often and over again that God is "spirit". Accordingly, when one understands that the term "God" is simply a description given to an infinite entity, the concept of what "God" is (essence wise), makes sense.

Note: Wind is a form of solar energy, which explains why wind, breath, energy are really within the same realm. This is why they all can be referred to as ‘Spirit’. The word for Spirit in biblical Greek and Hebrew is the same for breath, and wind. Therefore, be mindful that we take in the essence of God every time you inhale! It is God that gives life!
