Doesn't matter! He's God, He's in control, and He'll do what he wants. Here's more:
"...whoever drinks of the water that I will give him shall never thirst;" John 4:14
"I have food to eat that you do not know about." - John 4:32
"He who believes in Me, as the Scripture said, 'From his innermost being will flow rivers of living water.'" John 7:38
I don't think this is sound theology. God is "not willing" that any should perish, but many do perish every day. Yes, God does let sinful man determine his own fate and the fate of innocents around him. Injustice perpetrated by sinful man is a part of everyday life, and God does not always interfere to stop it.
