TIMING:

Ecclesiastes 3:1-4 says,

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

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 

Why do we wait? It teaches us to trust in God. We learn that His timing is Perfect. One of the facts we have to learn is this: 
GOD'S DELAY NEVER DESTROYS HIS PURPOSE 
and there's a difference between "no" and "not yet."

"But these things I plan won’t happen right away. Slowly, steadily, surely, the time approaches when the vision will be fulfilled. If it seems slow, do not despair, for these things will surely come to pass. Just be patient! They will not be overdue a single day!" (Habakkuk 2:3)
