OK. Why do you submit the situation or person to God? Is he otherwise unaware of their plight? If he's going to intervene in the world, wouldn't he do it with or without your prayers?
I think he often may well do that.
I guess if he just sorted out everything without any input from anyone - then there would be no need for us to care for others, pray for them, think of them, or feel empathy for them or their situation.
Every time someone we knew was being hurt (or hurting someone else) we would just ignore it and think to ourselves -hello...God... Im tired of looking at this - sort it out already! and because we knew God would do it all we wouldnt even bother to care
Again, if you were a parent, as an example - you could do everything for your child. You could also give them every material thing they might want the moment they asked for it
But is this really the way to be a loving parent? Denying your child the chance to learn to care for others, to learn to work for something, to problem solve, make moral decisions or analysis, figure out what is wrong or right, or even just the anticipation that comes from spending time saving for something you cant just buy outright?
Most parents I know would agree that along with giving their children love and food, shelter, etc and material gifts, they also as loving parents - sometimes let their children be exposed to painful things - to help them understand and emphasize with other peoples situations
I am thinking that if it were me asking your question i would go - well thats all very well but if my kid were about to fall off a cliff, or get raped or murdered by terrorists, get into a car and drive drunk or die in a famine in africa while the western world wastes untold amounts of food daily- then I would NOT just stand by and let them learn from that - Id act! And therefore why does God let horrible things happen to innocent people?
I could theorize that its because of free will - the people who make the decisions to do things which result in the rape, murder, terrorist attack, famine, etc
Or I could theorise that maybe in Gods eyes as our time on earth is so miniscule compared to eternity in heaven that he thinks
"so what if that happens - hello? 30-70 years of crap compared to more than 28347832749832749832794732984732988579328579328475893475934875983475893475938475983475983479++++ years of happy joy and plenty...... who is winning long term heh?
And various other theorys
Or I could be honest and say though I may sometimes have my own theorys or ideas that I think God gave me the truth is I dont for sure, know.

Can only suggest you put that question to God directly yourself and challenge him to show you the reason... (maybe throw in a teaser and offer to consider letting God save you if he can enlighten you on some of this stuff)
