Seeking spiritual-religious songs from popular scene

I love my new church job.  It is at an open and welcoming congregation of "kind, unpretentious people trying to live gratefully in response to God’s many gifts" (per their website). By my interactions over the last two months, I can say honestly "they are who they say they are."  Gotta love it.

One of my tasks as the Music Director for their new Progressive Service is to seek out music that doesn't typically find itself in the worship service, but whose words resonates with a meaningful spiritual life.  How cool, right?!?  I thought so too. 

Want to join my fun in looking for such songs?  I'd love to have you along for the ride -- there's millions of songs on this planet and I only have two ears.  In particular, I'm looking for songs that fit into one of the themes for the year:

• Advent Conspiracy
• Marriage Equality & Full Inclusion
• Haiti
• Reconciliation (during Lent)
• Being Green & Earth-friendliness

Leave the title and/or artist of a song or YouTube link in a comment under this post.  From time to time, I'll share some of what I find too. 

Blessings!
