Ecclesiastes 9:10 says, Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.  People were not created to be idle, but to care for and have dominion over the earth.  There may even be times in our life when others get upset because they feel that we are working too hard.  We do what our hands find to do instead of looking for ways to avoid doing anything, and others feel this makes them look bad or that more will be expected of them.  As followers of Christ, we have an obligation to do our best by our employers.  In our own lives, we have a responsibility to do what God gives us to do as long as we are able, because as we get older, ability decreases until at death we can do no more.  As long as we do everything for the glory of God, we will always do our best.  Verse eleven says, I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favour to men of skill; but time and chance happeneth to them all.  I believe Solomon was saying that life doesn't always go according to plan and expectations.  We have seen races where the fastest was winning and suddenly tripped, and someone else won the race.  Sometimes, simple overconfidence in ones own ability can lead to failure.  We cannot put our faith in the things of this world, but must trust the guidance of God.  Ultimate victory is assured if we do, no matter how many failures we experience in this life.  Verse twelve says, For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are caught in the snare; so are the sons of men snared in an evil time, when it falleth suddenly upon them.  We cannot know the time of our death, but we can be tempted into actions that may lead to death much sooner than would be normal for a person.  Fish tempted by bait or just unfortunate enough to be swimming where a net is cast die sooner than those who don't take the bait or get caught by the net.  Some actions we take can lead to a sudden, unexpected death, while at other times just being in the wrong place can cause our death.  We may feel that we live in an evil time, and for so many people in the world today, that is especially true.  Still, we as God's people, must not live in despair, but in hope through Christ.
