Deep spiritual love song

The song I found when I was looking for a youth devotional "put light on the lamp" a "interlude" for a ppt about. The text can of course be seen as a very touching love song - for me it is much more like a modern psalm, which would also be a "Kyrie" very appropriate in a church service. For this, the truly professional performance of this group that I just very responsive person. Rich, full sound, anyway not to pathetisch- a song that moves greatly.
