How do you reconcile your just and loving God with someone who created bone cancer in children, for example?
That's pretty much the most extreme example of individual suffering we can imagine; a small child in their (relative) innocence, suffering from a painful illness that seems to strike at random, and that may ultimately kill them. How can God allow that? It's a good question. The answer is not simple or presented glibly, I can assure you. We've all seen suffering. We've all lost loved ones. Most of us have suffered pain.
I'm hoping the question is not too close at home for you. If I knew you in RL I'd know your circumstances. I'm assuming you're asking a philosophical question rather than typing into your phone while at a hospital bedside. Because if it is very personal, then theological debate can wait.
The question of suffering is one we all struggle with.
God made the world perfect, and people have ruined it. He gave us free will, and people used that to mistreat each other, destroy the environment, and act selfishly. The result of that is that much of the suffering in the world is man-made: war, famine, land for crops destroyed, seas and air polluted, violence etc etc.
But most suffering seems random. Jesus addressed this when some people asked him why a man had been born blind: had he sinned, or was it his parents' fault, they asked? Jesus's reply was that neither was the case. His blindness was not a punishment for something he or his family had done. It was a result of the world being 'fallen', that is, ruined or destroyed by the selfishness of people in general.
It's impossible to say why a particular person may get cancer: it could be environmental - who knows what damage pollution causes?. It could be genetic - a fault in a gene that's passed on through generations. But I think I can be definite that while mankind in general might have ultimately caused the genetic / environmental damage, it's not the fault of the sufferer himself. I suppose there are in some cases lifestyle factors, but probably not in the case of a child.
So a consequence of God allowing us to choose our behaviour, is that bad things happen and random illness will occur.
God could have prevented this, but only by not allowing us any freewill. We'd then be automatons, acting almost like robots.
There are other arguments why suffering occurs. Some of them seem flimsy to me, some of them are hard to hear.
For example: God uses suffering to draw people to himself. Not that he deliberately inflicts it, but he uses the illnesses we suffer to turn our thoughts to the 'why' questions we all have. I think this is a pretty poor argument. It may be true that people do sometimes turn to God for comfort, but I dont think it explains why suffering happens in the first place.
Or there's this: it gives an opportunity for people to help and comfort each other. Again, I'm not sure that's a reason why, it's more of a consequence.
So overall, I would say God ALLOWS suffering rather than inflicts it. If he didn't allow it, he would have to make us slaves to his will by denying our free will. That's not fair or loving either.
It's a tough subject. Why do you think children get bone cancer? Is it chance? I'd be interested in seeing a non-God way of looking at it.
If you want a better explanation than mine, C S Lewis wrote a really moving and tender book on this subject, called The Problem of Pain. He doesn't give simplistic answers. He knew a lot about bone cancer, sadly. You might find it interesting.
