Remember Jesus, for whom and by whom all things exist

For it was fitting that he, for whom and by whom all things exist...Hebrews 2:10a

In this series, I'v already talked a bit about Christ's presence in creation. He has always been, and He has always been God. There is no created thing outside of His control because all things have been created by Him.

He is the image of the invisible God, the firstborn of all creation. 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. Colossians 1:15-17

Christ was at work in creation! He did not suddenly appear on earth as Mary and Joseph's baby boy; rather He has always been laboring for our good and His glory.

This brings me more to the why, the for Him. The first questions and answer of the Westminster Catechism reads:

Q: What is the chief end of man? 
A: To glorify God and enjoy Him forever 

Creation, then, exists to glorify God!

The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge. Psalm 19:1-2

So, creation not only sings Christ's praise, but also makes Him known to us -

For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. 
Romans 1:19-20 

In Jesus, we have everything we need to know in order "to glorify God and enjoy Him forever". He has not hidden Himself, but has in fact made Himself known to us in all things.

The God who made the world and everything in it, being Lord of heaven and earth, does not live in temples made by man, nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything. And he made from one man every nation of mankind, to live on all the face of the earth, having determined allotted period and the boundaries of their dwelling place, that they should seek God, and perhaps feel their way toward him and find him. Yet he is actually not far from each one of us, for "In him we live and move and have our being"; as even some of your own poets have said, "for we are indeed his offspring" Acts 17:24-28
