Why do bad things happen to good people?

"Good" or "bad" is your perception. Adversity can actually be seen as a gift. Many cancer survivors will tell you, "It’s the best thing that ever happened to me".

Divinity is omniscient and you are not. Your perception is not Reality. What you perceive as "unfair" might just be the means of liberation.

What you’re wanting to know is whether there is intrinsic justice in the world and whether happenings in the world emerge justly and fairly. Yes, they do. Human life is karmically fair, completely and totally. Everyone is steering their own canoe.

As Love is the Ultimate Law of the Universe, each person is born into the circumstances of maximal spiritual benefit.
