And let the peace of Christ rule in your hearts, to which indeed you were called in one body. And be thankful. Colossians 3:15 (ESV)
We are reminded often to be thankful in Colossians. Although God does not need our thanks, we benefit from being thankful. It is important to remember our own helplessness and dependence on God for everything that we have, especially the salvation which we have received as an unearned gift.
