Creation Day 4.
God created lights in the sky. The sun, moon, and stars are made by him.
I can walk the street at night because he gave me the twilight. If the world would be without light, I couldn't walk and write something down, and see the faces of my favorite people, like my mother and my friends. So I appreciate him so that I can spend a quality time on my favorite things, doing anything freely (without worrying) day and night.
What is the most grateful things that you have lights?
