Lyric discussion by Jesuz_luvs_u 

Hmm, Im trying to work out the exact meaning of this song and am finding it somewhat difficult.

It seems to be about the writers experience as someone who files regularly, and who saw on the plane near him a woman he recognised, so he smiled at her. As he did this, there was hope in this lady's eyes and later in the conversation she commented "you seem so different to me". The artist seems to ponder "what's different now?" that caused this lady to suddenly notice there was something about the writer, when as far as he was concerned "everything's the same" as normal. He concludes that it is the power of a smile "that the world around me seems to understand", and its that "joy inside" which speaks of the love of God, which causes people to see soemthing different about us as Christians. "With one smile I could see The faith we share inside"
