I did this somewhere else many years ago and was shocked that most said no. Please comment if you will.
With Hawaii , Guatemala, last years three major US Hurricanes please vote if you believe either God controls these things or it is just some random natural events...Thanks
"God saw all that he had made, and it was very good."
God made Nature, so Nature works.
Instead of an unworkable machine poorly designed...
His creation is truly amazing and wonderful.
Nature works, it functions, beautifully.
So, He does not have to constantly make it work it seems.
But...at the same time, He is behind all of creation, the very laws of physics, and can sweep the old away and replace it whenever He wants.
So, He doesn't need to make a butterfly's wings function. No need to control such things.
So, asked so broadly: Does God have to make everything work all the time? That answer is very likely: No.
Because
He already has made it work.
He is in ultimate control though. He is in ultimate control of the ultimate outcomes that matter. He can intervene in nature at any moment.
