I would classify this as contemporary christian rock.
I like the song a lot. I think the bells are ok but you might consider using a steel drum sound or another percussive melodic instrument. Just experiment till you find what seems to work best.
The mix is not too bad and I like the vocal harmonies.
I agree with the previous poster that the vocals "na na" in the beginning could be done without and wait for the lyrics.
You have a solid performance here so once you settle on the sounds etc the mix should come together nicely.
I have not been around here much either in the last 2 years so its good the hear a familiar voice.
