Ecclesiastes 3: 1-11 NIV
There is a time for everything,
    and a season for every activity under the heavens:

2     a time to be born and a time to die, a time to plant and a time to uproot, 
3  a time to kill and a time to heal,
    a time to tear down and a time to build,4  a time to weep and a time to laugh,  
a time to mourn and a time to dance,
5     a time to scatter stones and a time to gather them,
    a time to embrace and a time to refrain from embracing,
6     a time to search and a time to give up, a time to keep and a time to throw away, 7  a time to tear and a time to mend,
    a time to be silent and a time to speak,
8     a time to love and a time to hate, a time for war and a time for peace.
9 What do workers gain from their toil? 10 I have seen the burden God has laid on the human race.
 11 He has made everything beautiful in its time. He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end.
