Energy
The Law of Conservation of Energy states that energy can be absorbed and released, but it cannot be created or destroyed. It simply assumes a different form.
This reminds me of God. We didn't make Him, we cannot destroy Him. We can absorb Him and release Him to others, we can accept Him or reject Him, but He is still there. I think God's energy is in all of us, just in different forms. Like my good friend C.S. Lewis once said, "God has impressed some sort of likeness to Himself, I suppose, in all that He has made."
