Matthew Henry on 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.
