There is a time for everything, and a season for every activity under the heavens:

a time to be born and a time to die,
   a time to plant and a time to uproot,
 a time to kill and a time to heal,
   a time to tear down and a time to build,
 a time to weep and a time to laugh,
   a time to mourn and a time to dance,
 a time to scatter stones and a time to gather them,
   a time to embrace and a time to refrain from embracing,
 a time to search and a time to give up,
   a time to keep and a time to throw away,
 a time to tear and a time to mend,
   a time to be silent and a time to speak,
 a time to love and a time to hate,
   a time for war and a time for peace.

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.

Ecclesiastes 3
