unclaimed treasure, or left luggage?

See this pic?
This, apparently, is me.

Am somewhat bemused by a post-church conversation over coffee.  The topic of conversation happened to be on the matter of lawn bowls [gads, I feel sooo middle-aged] but somehow relationship status entered the scenario.  I noted that 'as a single person, yadda yadda, yadda.'  My conversational counterpart responded with:
'Ah! You're one of God's unclaimed treasures.'
Marvellous.
I did respond, with a grin, that this was not quite correct: 'God has claimed me for his own.'
In a later conversation with some of the RevGals, a consensus was building that, perhaps the above was marginally better than being referred to as 'left luggage'. 
Regardless, I now feel the need to create a badge to wear, with the words 'God's unclaimed treasure' boldly emblazoned upon it.
Or, alternatively, written on a cardboard luggage label; after all, they're cheaper...
