Remembering our Triangle Visual, we can know that God was before all Creation: 'Christ is the visible image of the invisible God. He existed before anything was created and is supreme over all creation' - Colossians 1:15. This serves as the beginning in our quest to Know God.
Yet, it pleased Him to Create and His Creation began with the world (both seen and unseen): for through him God created everything in the heavenly realms and on earth. He made the things we can see and the things we can't see--such as thrones, kingdoms, rulers, and authorities in the unseen world. Everything was created through him and for him - Colossians 1:16. This is the physical evidence of our Creator.
We can know the loving care of our Creator as we understand that the Creation was given to us as a beautiful gift to steward: Then God blessed them and said, Be fruitful and multiply. Fill the earth and govern it. Reign over the fish in the sea, the birds in the sky, and all the animals that scurry along the ground. - Genesis 1:28. Here is the vocational aspect of the Creation. We were given a job and, unlike many job situations, this one would bring us joy.
Vocation gets a bad wrap. God didn't leave man idle in the garden because, as always, He knew what was best for us. We are designed by Him as very purposeful. This is a critical component to how we serve Him and how we fulfill our own quest for meaning in this life.
This isn't limited to what we do for our '40-hour work week' but it certainly does include it...or it should. Do you look at your vocation as a way to please God and fulfill why He placed you on the planet? I will suggest that, no matter your work, it can be done to honor God and to bless others.
Many years ago, I worked in the janitorial industry. Many others looked down upon the work I did but I found great fulfillment in it. Why? It was work that needed to be done and rarely did others want to do it. Finding joy in your vocation comes from receiving joy from your Creator. Here is a great promise to consider in regard to this: Work willingly at whatever you do, as though you were working for the Lord rather than for people - Colossians 3:23.
