Why Wait?

"Sisera, who had 900 iron chariots, 
ruthlessly oppressed the Israelites for twenty years. 
Then the people of Israel cried out to the Lord for help."
~Judges 4:3

Does your mind stick at then, too?
Twenty years before they broke?

Back in Judges 3:7-9, it says,
"The Israelites did evil in the Lord's sight. 
They forgot the Lord their God, 
and they served the images of Baal and Asherah poles... 
He turned them over to King Cushan-rishathaim... 
and the Israelites served him for eight years. 
But when the people of Israel cried out to the Lord for help, 
the Lord raised up a rescuer to save them."

"Once again, the Israelites did evil in the Lord's sight, 
and the Lord gave King Eglon of Moab control over Israel 
because of their evil... 
And the Israelites served Eglon of Moab for eighteen years. 
But when the people of Israel cried out to the Lord for help, 
the Lord again raised up a rescuer to save them."
~Judges 3:12-15

They seem to have grown in their tolerance of oppression,
and to have grown dull in their remembrance of the Lord's help.
But there He was, after all those years of being forgotten,
with ears open for their cry of desperation,
ready to save them.
