Ecclesiastes talks about a few big ideas in the book. It is written by King Solomon at the end of his life. He discusses how everything in life passes away. Also, how everything has their own time and season in life. There is a time for death, work, and life each has its own season. His main theme centers around the "fearing God" because everything else passes away at the end of our life.
The book discusses the fleeting nature of life. Life passes away in an instant, but God is there at the end of time. Death passes away, toil passes away, and life passes away. The hardship we endure in life passes away as well. God never passes away; he is eternal.
The preacher says at the end of the book that God will judge all things at end of our life. Fearing God centers our life on God in the midst of life. God will bring everything under his control.
