Chapter 3 is among the better-known chapters in the entire Bible, and it is likely the best-known chapter of Ecclesiastes. It holds these distinctions partly because of the poem that begins it. Its subject is of great consequence to us.
A major lesson for us in this chapter is that we live our lives within time, and therefore, we make our choices in life within time. However, to make the best of life, we must recognize that God is sovereign over time—all the time. His rulership, His dominance, His sovereignty, over time is never relaxed. He oversees what happens within time all the time. His relationship with His children is very personal, making His calling personal and individual.
As Creator, He has goals that He set before the foundation of the world. They will be accomplished within an already set time. His goals also include what He desires to accomplish in and through us. A reality we must face is that time is always moving; time is running out for all of us. This fact is not intended to make us feel a sense of desperation, for God is so perfect and dominant over His creation and labors that He always has enough time. We, though, do not—a fact that God always takes into consideration. We can deal with this truth in our relationship with Him. This is where the issue of contentment can be quite helpful.
