I doubt he knew the woman, he was just being nice and saying hello. However, I think the main focus of the song is not on the girl specifically, but on what the two of them had in common: the light of God.

It also is showing joy in knowing that he is not the only real christian left in the world, because at times it really feels like that to me.
