The main purpose of every created thing or being is to praise God and give Him all the glory due His name.  Colossians 1:18-22 states that every created thing or being has been reconciled to God by the Blood of Jesus and Hebrews 13:15 lets us know that in response to all Jesus did to reconcile us, we are to sacrifice praise to God continually.  Receive an understanding of how our motivation should be to praise God with the fruit of our lips giving thanks to His Name.
