God the Son was important in the creation, and in sustaining that which He created!
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made through him. Without him, nothing was made that has been made. 10 He was in the world, and the world was made through him, and the world didn’t recognize him. 12a But as many as received him, to them he gave the right to become God’s children . . .
Colossians 1:14 in whom we have our redemption, the forgiveness of our sins. 15 He is the image of the invisible God, the firstborn of all creation. 16 For by him all things were created in the heavens and on the earth, visible things and invisible things, whether thrones or dominions or principalities or powers. All things have been created through him and for him. 17 He is before all things, and in him all things are held together.
Hebrews 1:3 His Son is the radiance of his glory, the very image of his substance, and upholding all things by the word of his power, who, when he had by himself purified us of our sins, sat down on the right hand of the Majesty on high ...
(Although the passages above indicate that God the Son was the most important agent in the creation, there are scriptural indications that God the Father and God the Holy Spirit were also involved.)
Perhaps you and I don't fully appreciate the magnificence of creation, and, therefore, we may not fully appreciate the magnificence of Christ.
Creation shows that God the son loves diversity. There are about 400,000 species of beetles, and probably at least a million yet to be discovered. (Psalm 104:24 Yahweh, how many are your works! In wisdom, you have made them all. The earth is full of your riches. 25 There is the sea, great and wide, in which are innumerable living things, both small and large animals.)
Creation is unimaginably large. “Recent estimates of the number of galaxies in the observable universe range from 200 billion [(2×10 to the 11th power) to 2 trillion (2×10 to the 12th power)] or more, … containing more stars than all the grains of sand on planet Earth.” (Wikipedia) And that’s only the observable universe.
Creation shows the power of God the Son. Most of the energy on earth comes from the sun. In the sun, Hydrogen nuclei bombard each other at several million degrees, and turn into Helium nuclei, releasing energy by e =m c-squared. The sun is about 93 million miles away. Since it is emitted in all directions, the vast majority of the sun’s emitted energy goes off into space, never hitting the earth, or any other body in the Solar System. But it’s warm enough for life on earth, and light enough for photosynthesis, just from the tiny fraction of the sun’s emitted energy that strikes it. We can scarcely imagine the power of the sun, and it’s a fairly small star.
Creation shows that God the Son likes beauty. He didn’t have to make the universe so that rainbows, or fall foliage, or butterflies, or eclipses, exist. But He did. Using scientific tools, such as microscopes and telescopes, we have found that there is amazing beauty, even in things we can’t get to, or can’t see with the naked eye.
God, the Son’s, creation is beyond our imagination! He created time and space! God created matter and energy! God created the four fundamental forces, (also called the four interactions) – gravity, the electromagnetic force, the strong force and the weak force. God created the entire electromagnetic spectrum: light, radio waves, wi-fi, microwaves, X-rays, and more. God created the universe with appropriate physical properties for the existence of life
We should not forget that, even though He was largely responsible for the creation of the entire universe, He came to earth. Not as a baby, but as an embryo, a being with just a few cells, and hardly any connection to the world outside his mother’s womb. Then, of course, He became a fetus, and, after about nine months, a baby. Still helpless, dependent, and, presumably, severely limited in His ability to communicate.
And we should not forget what St. Paul said about the Creator and Sustainer of the universe:
5 Have this in your mind, which was also in Christ Jesus, 6 who, existing in the form of God, didn’t consider equality with God a thing to be grasped, 7 but emptied himself, taking the form of a servant, being made in the likeness of men. 8 And being found in human form, he humbled himself, becoming obedient to the point of death, yes, the death of the cross. 9 Therefore God also highly exalted him, and gave to him the name which is above every name, 10 that at the name of Jesus every knee should bow, of those in heaven, those on earth, and those under the earth, 11 and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (From Philippians 2)
