Not so much religious as spiritual. I believe that the universe is sentient to a certain degree, and that being in a positive mood attracts positive experiences. This isn’t theoretical for me; I’ve seen it work for me countless times, and I know how to best make use of it (e.g. manifestation rituals, gratitude practices).
I believe that we don’t inherently “deserve” anything, good or bad, but that we get what our “vibe” is asking for. Miserable people attract more misery.
