I don't know about the religious stuff, I think it's most likely just used for metaphorical reasons.
This song is amazing. Personally, I think it's about the main character (the person the words would be coming from) having 'slept around' quite a bit during another relationship, possibly one that didn't mean too much to that person. Then, something came over the person and they realized their error and that they actually did love the person they had the relationship with, and this song would be the apology.
