Genesis 2:1 “And the heavens and the earth were finished and all the host of them.”
Genesis 2:1 cannot mean that there are no more celestial bodies today than there were then, because we know the universe is expanding and new stars are being formed all the time. It also cannot mean that God got everything set in motion and now the created order just carries on by itself making new celestial bodies and doing all that God programmed the universe to do, because that is deism.
God made everything and He finished creating and what He created was set in motion so that the universe continued to expand and make new celestial bodies according to the laws that God had made. But when a new star or planet or comet or anything comes into being it is because God is actively doing something. The universe continues to expand because God is expanding it. New stars are forming because God is forming them. Laws of physics exist because God made them and they are predictable, not because they have always acted in a certain way. They continue to be predictable because God sees to it on a constant basis that they behave in the way He created them to behave.
Hebrews 1:3 (ESV) He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high, Col. 1:16-17 (ESV) For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities-all things were created through him and for him.  And he is before all things, and in him all things hold together.God finished it and God maintains it, despite all that sin has done, even to the creation itself (Romans 8:18-25).
Today, you will witness many laws of nature at work. Remind yourself that they behave as they do because Jesus Christ upholds all things by the Word of His power. Before they are the laws of nature they are the laws of God for the natural order. Then lose yourself in the wonder that you are in the care of the One who holds the planets and stars in their places. Worship will cease to be something you have to force yourself into.
