Obedience 

"When obedience becomes our goal, it is no longer an irritation; instead of a stumbling block, it becomes a building block."

James E. Faust 

I think that this means that if you do the right thing, things will work In your favor, like for example if you see someone drop there wallet you can pick it up and walk over to them and give it back to the owner and they might give you a reward for doing the right thing.
