Need help understanding Nepali song

Is there anyone here who understands Nepali? Mine is rudimentary at best. I’m trying to figure out the themes of this song Hey Pita. It is a Christian song, so familiarity with those words might help.

(And no, it’s not about greeting a piece of bread. “Hey Pita” means “O Father”, and it’s followed by “Hey Yeshu” [Jesus]. That’s about the limit of what I know.)

I’m not looking for a full translation, just what the general theme of the song is, or if you can, what the first couple of verses cover. I’m looking for a song that fits in with the idea of salvation or redemption.
