1. You cannot understand the work of God (1-6)

In these verses, the Teacher expounds on the idea that we cannot understand or predict the outcome of this life that God has given us. He urges us to invest in many measures because disaster may unexpectedly befall some of our investments. If we ship our grain overseas, we will soon receive a reward. So the Teacher urges us not to be idle, but to work hard, for we don't know which of our endeavors God will bless.

2. Enjoy the years God gives us (7-10).

These verses are full of talk about joy and light. We don't know how many years God has given us on this earth. Many of our days will be dark and meaningless. But God wants us to be happy and for our heart to give us joy. We should follow our hearts, but remember to fear God as we do.
