Solomon came to understand that man knows very little about how God works. In chapter 11 he begins to encourage those who would read and hear these words to “ cast their bread upon the waters” and it will return to you. This speaks of being generous toward others and having faith to sow into the lives of others.
Solomon reminds us that the mysteries of God are often hidden from man. Man cannot answer how a child is formed in a mother’s womb; nor how a day will turn out. He cautions young people to be careful not to follow your heart or desire what the eyes behold because God will judge us for living that way. He ends this chapter by encouraging people to remove evil from our flesh for this leads to vanity. These words of wisdom come from God. We would be wise and blessed to obey them.
