And does that mean...? That God decided it should die, or instead that God is aware of it? Does God have to manage every tree, every organism, or did He make them working on their own, by His design?
Usually, it seems to me, people don't want to admit that God is in all-control . . . even of humans; because ones don't want it to be true that they themselves are not really in control.
But you say, "Does God have to" > if you feel loaded down with too many things to take care of, keeping track of every single tree in a forest might seem too much to handle. Therefore, you might feel it could be too much for God to bother with?
But God is caring; whatever He does is caring. You, I think, know how while you are doing caring things, it is not a burden, or not as much. God, I think, is a micro-Carer . . . like a micro-manager, except He is caring for every electron flying around a nucleus . . . or through it. And He is fast enough to make it happen and keep track of it all.
The fact that physical things keep on functioning the way they do, in spite of all the evil, is a direct demonstration which can help us see how stable God is, even while at His high level of function to maintain the universe, and how He is quite capable of taking care of us.
I think the later, but...I think also it's all more complex even in the physics (how nature works) than we think, also. My guess is He maintains physics itself, but this is guessing.
I understand that there is a reason why people of physics and medical science keep finding out that there is more to try to find out > because God's ways are "past finding out" (Romans 11:33), and these ways are now working in all His creation.
But even though we can't figure out His ways, these ways are living in His love; as much as we submit to living in God's love, we can benefit from these ways.
