If your child asks, "Why did God let that bad thing happen?"

"That is one of the hardest questions in the world, and it's okay to be mad about it. If God forced everyone to be perfectly good all the time, would we actually be free?"

God created a world where love is possible, which means free will is necessary. Because humans chose to rebel, the world is broken. God doesn't cause all the evil, but He promises to redeem it and suffer alongside us.
