I question why God would care at all about such things, when he has the whole universe to attend to.
I see the argument limiting God with humanistic inequalities. I don't see why God would have to tend to the universe where He has to juggle things.
There's nothing ambiguous about asking why he would care.
It is ambiguous because it has no satisfying answer for someone in your current philosophical position. "Why wouldn't He care?," then becomes just as applicable.
if we can understand what he wants, then we can ask why he wants it
That's why we are called to juxtapose scripture with everyday life.
We can also look back in the thread, to where this already came up. When I draw a picture, I don't really care about the ink's motivation for soaking into the paper; only that it does so.
The ink is only the mechanism that animates what is in the mind of the artificer, which makes the mention of the ink or pen almost ineffectual. The point is the skill and what lies in the mind of the artist. The pen and ink could do nothing without us.
But we can certainly wonder at the rest. Such as, say, off the top of my head, "Why would he care?"
Why would you care about your children? Wouldn't we be more likely to care about our children than not care about them? If God has invested the time to lay the groundwork for our lives, to bring His thoughts to life, isn't that sufficient reason to assume that God would care? I think the problem is that you don't know God so this is all unimaginable for you. Exactly what kind of answer are you looking for? I mean, not one of us can prove God to you or anyone else. That's the dichotomy for the believer. They know God exists, and yet, are incapable of proving that to anyone else. That's the dichotomy the believer faces. The most anyone can do is to live in rightstanding with God and be used as His vessel so people can see God in the believer.
How can I prove that God cares to you when you reject and forsake all the answers given by someone like Jesus? Look at Jesus, which is humanity at its greatest, when its reached the point of divinity, and then ask whether or not God cares. The entire gospel narrative is focused on God's love for us, a love so powerful that God would sacrifice Himself in our stead.
The problem is that you don't believe in the gospel narrative. Even if you don't believe that Jesus and God are one, doesn't the fact of his deep desire to heal us through his own massacre stir something in your heart? At the worst the unbeliever calls Jesus a deluded idiot who killed himself because he was naive to think he could change the world. But at best even the unbeliever can respect that kind of hope he instilled-- a devotion so deep that He would spend Himself for a people's that both love and despise Him.
"Somewhere at the back of my father's mind, at the bottom of his heart, in the depth of his soul, there was an empty space that had once been filled by God and he never found anything else to put in it... At the centre of me is always an eternally terrible pain - a curious wild pain - a searching for something beyond what the world contains." -Bertrand Russell
