Cover art for Shine On lyrics by Needtobreathe

I think this song is written from God's point of view. It's got so many references, including "I was with you in the valley" from Psalm 23, as well as "I am with you still", which i'm not sure is from. However, I believe this song is just an encouragement from God to His followers to keep persisting and shining on despite any obstacles they come across. He reassures them that it's okay to keep going, and not to forget about Him in their daily lives as they deal with the material things.
