Looking at the lyrics one can make a guess that the author was speaking to Jesus directly....though his name is never mentioned in the song. Doesn’t help anyone listening who doesn’t know about Christianity though I suppose it might prompt such a person to ask..”Who are you singing about?”
Watch the original videos - the sense that the band, and especially the singer, is worshipping rather than just performing is very strong. Only Jesus can inspire that level of worship IMO.
