I have not really been raised with religion in my life, but believe I am a spiritual person, I believe in God and something higher. My question is why do bad things happen to good people?

I believe things happen for us to learn from, but can't see the lessons in so many bad things. Today for example someone very close to me had $650 stolen from them, this person is the kindest most giving person, who helps people as a profession, and who struggles financially day to day.... what is the lesson in this?

Struggling to make sense of it all...
