Genesis 1:1 (NKJV)
In the beginning God created the heavens and the earth.
One of the philosophical arguments for the existence of God is call The Cosmological Argument which basically states that every thing that begins to exist must have a had a cause outside of itself. I love this verse because it so matter of factly ignores any requirement to defend the existance of God. It does this so powerfully and in such understated fashion that it reminds us of the absolute requirement that there had to be a first cause or a first mover for anything at all to exist.
Note the elements of time (beginning), space (heavens), and matter (earth), and energy (created). Simple thought starts out with simple ideas that matter itself was created, and that's no small feat. But notice that time and space are also created things. What was it like before time? What does it mean to not have space? That's God's environment, eternity. And that is why the Bible describes God as a spiritual being. The spirit is the other realm that has no dependence on our physical realm. That is also why Jesus says:
John 5:37 (NKJV)
And the Father Himself, who sent Me, has testified of Me. You have neither heard His voice at any time, nor seen His form.
Colossians 1:15-16 (NKJV)
He is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him.
So here is the most amazing thing of all: Jesus is the agent of creation and not did he only create time, space, energy and matter, but he created all the other dominions visible and invisible. This graceful and merciful savior we serve is also the Almighty God to whom nothing is impossible.
