“凡事都有定期，天下万务都有定时。”
虽然人生有很多事情包括生和死，都由不得我们自己，至少有一件是我们自己可以选择的，就是在自己劳碌的事情上喜乐。

我又见日光之下，在审判之处有奸恶，在公义之处也有奸恶。 (传道书 3:16 和合本)
And I saw something else under the sun: In the place of judgment—wickedness was there, in the place of justice—wickedness was there. (Ecclesiastes 3:16 NIV)
我心里说， 神必审判义人和恶人；因为在那里，各样事务，一切工作，都有定时。 (传道书 3:17 和合本)
I said to myself, “God will bring into judgment both the righteous and the wicked, for there will be a time for every activity, a time to judge every deed.” (Ecclesiastes 3:17 NIV)
我心里说，这乃为世人的缘故，是 神要试验他们，使他们觉得自己不过像兽一样。 (传道书 3:18 和合本)
I also said to myself, “As for humans, God tests them so that they may see that they are like the animals. (Ecclesiastes 3:18 NIV)

都归一处，都是出于尘土，也都归于尘土。 (传道书 3:20 和合本)
All go to the same place; all come from dust, and to dust all return. (Ecclesiastes 3:20 NIV)
谁知道人的灵是往上升，兽的魂是下入地呢？ (传道书 3:21 和合本)
Who knows if the human spirit rises upward and if the spirit of the animal goes down into the earth?” (Ecclesiastes 3:21 NIV)
故此，我见人莫强如在他经营的事上喜乐，因为这是他的份。他身后的事谁能使他回来得见呢？(传道书 3:22 和合本)
So I saw that there is nothing better for a person than to enjoy their work, because that is their lot. For who can bring them to see what will happen after them? (Ecclesiastes 3:22 NIV)
