God’s allowance of evil is frustrating for us, but it does not necessarily indicate indifference nor approval. In fact, God specifically communicated to the ancient Jews that he did NOT approve of evil acts and commanded that they not be done. He also entered into the world in human form and continued teaching while he lived and entering into our suffering and suffered great evil for our benefit. That doesn’t sound like an evil-approving or indifferent God to me.

We believe that God tolerates evil to bring about good. So, for example, he tolerates evil acts by men for the good of free will. Additionally, although he does not will evil acts, he is able to work them into his plan so that good may come of them. God is glorified by good, by seeing his creatures “fully alive” and prosperous. And so, in a sense, suffering can work to glorify God by bringing out more virtue and good in men.
Someone who has suffered and been victorious is much better for it than someone who has never suffered and never been tested. That is true at least in this world, with these fallen natures that we have.
