I don’t get it. Why does God just stand by and let such horrible things happen as go on in this world, when he could stop them if he wanted to? Doesn’t God care?
Yes, God cares. But I doubt anybody can give an entirely satisfying answer to that question. Here is what we do know: The way we best understand God and our suffering is to look at Jesus Christ. He is God; he is human, too. God became human, without ceasing to be God, for our sakes. That is what we mean when we say Christ was fully God and fully man.
