Is there any actual evidence that God cares for people in general, or Christians in particular?
I remember from my church-going days a proof given periodically by preachers of this. After preaching on God's care for his followers, the preacher would ask a question like this: "Is there anyone here who God has not provided for when you were in desperate need?" And of course no one raises a hand. Wow -- surely most people have been in some sort of great need during their lives, and if God provided for them then that's a 100% batting average on God's part. What more could you ask for?
There are a number of problems with this demonstration, and here is the big one that made me a bit uncomfortable even in much church-days. Say someone was in desperate need and God didn't provide. Well, he would die. And clearly there have been many Christians in desperate need of healing or something else to keep them alive, but didn't get it and died. By asking this question to the living members of his congregation, the preacher has effectively excluded anyone who could convincingly say "No, God didn't provide for me and I died." So if you exclude the nays, then it is not too surprising you will get 100% yeas.
The classic demonstration from nature that God must care for us is attributed to Jesus. Consider Luke 12:22-24: And [Jesus] said to his disciples, "Therefore I tell you, do not be anxious about your life, what you will eat, nor about your body, what you will put on. For life is more than food, and the body more than clothing. Consider the ravens: they neither sow nor reap, they have neither storehouse nor barn, and yet God feeds them. Of how much more value are you than the birds!" Granted, we are more valuable than ravens. And granted, I have not seen any dead ravens. I am not sure it follows that God feeds them in their need. If so the population of ravens would have exceeded all other birds by now. Rather it seems more likely that ravens die of starvation or thirst when food or water are scarce just like other animals. That puts a pretty big hole in the argument that God cares for us by analogy to ravens.
Instead of discovering evidence that God cares for those in need, the opposite seems to be the case. There is so much needless suffering in this world, and so many untimely deaths. Here I am not addressing the problem of suffering; I just want to find some positive evidence that God cares for those in need. Anecdotes of good coming out of times of desperate need are encouraging, but have to be balanced by the innumerable times desperate need leads to tragic death. So I am at a loss in finding evidence that God cares for you and me.
