Waiting for just the right time

Eccles. 11:3-4

3 If the clouds are full of rain,
they empty themselves on the earth,
and if a tree falls to the south or to the north,
in the place where the tree falls, there it will lie.
4 He who observes the wind will not sow,
and he who regards the clouds will not reap.

• How can you know how much rain will fall from looking at a cloud?
  
• If a storm comes, what can you do about it?
  
• If the storm uproots a tree, what can you do about it?
  
• Who determines the amount of rain you will receive?
  
• Who determines which way the wind will blow the tree?
  
• When will a person sow seed if s/he waits for just the right time?
  
• When will a person reap if s/he waits for just the right time?
  
• How do you choose between waiting for just the right time and the need to do something?
  
• At what point in life do you have to make a decision and trust God?
