Ok, maybe other people hear songs and the the light turns on like; wait a minute, thats a verse from the bible!
For me it is the other way around... I join singing the worship songs (I love the songs they sing here) am thinking; wow those words are awesome! Im singing them all day long and then after a while I discover as I read my bible that it comes straight form the bible LOL that makes me even more excited! whoohooo.
So if you have read a worship set with Misty Edwards...yesterday I read a verse in the bible and discovered the secret ;-) I found the bible verse which she took for the song hehe ;-)

For the Lord does not see as man sees; for a man looks at the outward appearance, but the Lord looks at the heart
