a very 'safe' lyric

I didn't get called in to work today, so instead of doing the washing, I sat in the coffee club and wrote this lyric (posted just below).

We're looking at 2 Corinthians in church and at bible study at the moment, so I tried to write something inspired by that. This kind of is.

A few questions ...

• Does it matter that I jump from 'we' to 'I'?

• I've used some form of the word 'safe' 12 times in this three verse lyric. Overkill?
  

• Does it's subject matter demand that it be given a tune like this? If so, forget it.
  

• With a decent tune, is this something you'd actually want to sing in church?

• Any ideas for the 'something else' in verse 3?
