Genesis 1:1 informs us that "in the beginning, God created the heavens and the earth..." The apostle John (1:3) tells us, "The world was made by Him. Not one thing that exists was made without Him."
See if you can find what NASA refers to as "The Eye of God" and the "Hand of God" nebulae. Look for Messier 104, one of the Milky Way planets and its satellite, and try counting the meteors and stars. Then multiply that times 10,000,000,000,000,000,000,000,000 and you MIGHT be getting closer to the number of celestial objects that He merely spoke into existence!
The psalmist, David, wrote a beautiful psalm about the night sky and how it "declares the glory of God and demonstrates His handiwork." Night after night it makes Him known to everyone who has ever lived on earth. (Read more of Psalm 19!) In fact, there are many, many passages of Scripture that convey this message and expand on this theme.
