So where do you put your sins?
Please do not quote me as saying "suffering of children is a good thing." What I meant to communicate to you was that some things are good and some things are bad, which I called triumphs and trials. When things are good, "God is good." But even when things are bad, "God is good." I may not completely understand why children are suffering, so the complete phrase/response is, "God is good, even though I cannot understand why this is happening." This response is very different than saying, "God is good, and it is good for children to suffer." Hopefully that clears up any misunderstanding.
Please answer the question if you will - where do you put your sins?
Another thing to point out, is that God does not cause evil, but He
can use an evil event for His purposes.
For example, perhaps an unsaved person grabs a gun and murders an innocent person. Said person gets put on Death Row, and while on Death Row, they have a lot of time to think and they know exactly what day they will die. They are overcome with guilt and they turn to Christ and become saved. This won't stop the execution from taking place, of course.
Now, in this example, God used an evil act (the murder) to bring about something good (bringing another soul to Heaven). As for children getting abused, raped, etc? That's a huge can of worms... God does not cause these children to get abused, though all things are allowed by God. Perhaps if He were to stop that from happening, something else worse would happen somewhere else? Perhaps the scars of the abuse would lead the child down to an eventual end where the child gets Saved in the future, and if the child did not have these scars, they wouldn't have gotten saved?
See, what we do in this mortal realm is like a grain of sand against Eternity. Too many people think that Life and Death here on Earth is the be-all and end-all of everything, but it isn't. If a child suffered horrible things, well... that's horrible... however, if said suffering lead to the child's salvation, is it not better for the child to suffer for a short time and spend eternity in Heaven, than for the child to have a good childhood, but wind up in Hell instead?
The suffering of the child is bad... but the end is good, rather than the childhood being good and the eternity being much worse than anybody can possibly comprehend while we're in our mortal bodies.
We can't judge these things, because only God foreknows everything. From the very beginning to the very end, He knows everything that is happening, that was happening, and that shall happen in the future. I was an abused child myself; I had a sexually abusive older brother. I'm 35 now, and these things happened between the ages of 5 and 13. It very much affected how I turned out, and when I came to Christ this past March, I said a long prayer of forgiveness, forgiving people who had done wrong to me, and my brother was one of the very first at the top of the list. I hold nothing against my brother now. He wasn't even 18 yet, and that was 20+ years ago, it's in the past, and done.
Furthermore, if I had been more successful in the world... would I have found Christ? Would I have become saved? If I could go back and do it all over again... I'd gladly suffer such abuse again if it meant that I'd end up getting saved if the alternative was to have a good childhood but end up in Hell instead because I was too successful in the world to notice Christ's calling. I think back on my life, and I can see the things He either did, or allowed, to bring me to my present location, and there's so many things that might have altered my path that He very much did not allow (some of THE strangest things happened to shoot some of my plans in the foot that came out of seemingly nowhere).
