Is There Such Thing As Luck?

I watched a movie today while Piper was home sick with Enterovirus (?) and it was about luck. I personally don't believe in luck. I believe in karma (the spiritual kind) where you do good things and good things happen to you. I believe if you do good things for others the world with work together for your good. I believe the more more active in the church you are the more "lucky" you are. I know from personal experience the less I practice these things the more "unlucky" I am. Well Piper is sick and crying and that is all the time I have. .. there is a thought, Windypops.
