I put this up with the words so you could get the meaning better, but go also and see a "live" version, as the Martins are great singers.
The words of this song are of Jesus talking to all us believers. Great reassurance, deep meaning, and a beautiful message when we are up against the world, and we think we are alone, and no one cares. But He cares, and we are never alone.
Jesus made a promise!!!
