Trees are pretty resilient. If you cut off their branches they will grow back in time. Some trees will even sprout again after being cut down completely. On the other hand, human life is short and death if final. And that's the message we here from Job in today's reading.
"But when a man dies, all vigor leaves him; when a mortal expires, where then is he? As when the waters of a lake fail, or a stream shrivels and dries up, So mortals lie down, never to rise. Until the heavens are no more, they shall not awake, nor be roused out of their sleep." — JOB 14:10-12
