That was just an excerpt of Colossians chapter 3 that instructs us as believers to put away our old ways and take on the new image given through our rebirth in Christ. This passage makes it very clear that we are to live with a constant heart of gratitude. That we are to focus our hearts intently on Christ in all things and at all times. Doing everything as an act of praise and thanks.
Webster's dictionary defines Thanksgiving as the act of giving thanks; a prayer expressing gratitude; a public acknowledgement or celebration of divine goodness.
My prayer for this Thanksgiving Day is that we not make the celebration a one day event based on the history of this country. But in turn that we approach each day as a day of thanksgiving. A day when we are grateful in our prayers, actions, and acknowledgement of God.
