9 What gain have the workers from their toil? 10 I have seen the business that God has given to everyone to be busy with.

11 He has made everything suitable for its time; moreover he has put a sense of past and future into their minds, yet they cannot find out what God has done from the beginning to the end. 12 I know that there is nothing better for them than to be happy and enjoy themselves as long as they live; 13 moreover, it is God's gift that all should eat and drink and take pleasure in all their toil.

Matthew Henry's Commentary on Ecclesiastes 3:9-13

Commentary on Ecclesiastes 3:1-10

(Read Ecclesiastes 3:1-10)

To expect unchanging happiness in a changing world, must end in disappointment. To bring ourselves to our state in life, is our duty and wisdom in this world. God's whole plan for the government of the world will be found altogether wise, just, and good. Then let us seize the favourable opportunity for every good purpose and work. The time to die is fast approaching. Thus labour and sorrow fill the world. This is given us, that we may always have something to do; none were sent into the world to be idle.

Commentary on Ecclesiastes 3:11-15

(Read Ecclesiastes 3:11-15)

Every thing is as God made it; not as it appears to us. We have the world so much in our hearts, are so taken up with thoughts and cares of worldly things, that we have neither time nor spirit to see God's hand in them. The world has not only gained possession of the heart, but has formed thoughts against the beauty of God's works. We mistake if we think we were born for ourselves; no, it is our business to do good in this life, which is short and uncertain; we have but little time to be doing good, therefore we should redeem time. Satisfaction with Divine Providence, is having faith that all things work together for good to them that love him. God doeth all, that men should fear before him. The world, as it has been, is, and will be. There has no change befallen us, nor has any temptation by it taken us, but such as is common to men.
