I think this song is about how we abandoned God's love and fell into sin and no longer have faces(Adam and Eve). It's kind of asking God for help to live again from our fallen, faceless state and Gods answer was Jesus dieing on the cross to forgive us for our sins. Cause without you I don't exist shows what we are without God and how we need him to replace/redeem us from our sins.
