Psalm 107:1 (NIV) Give thanks to the LORD, for he is good; his love endures forever.
Colossians 3:15-17 (NIV) Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful. 16 Let the word of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns and spiritual songs with gratitude in your hearts to God. 17 And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him.
Fulton Oursler tells of his old nurse, who was born a slave on the eastern shore of Maryland and who attended the birth of his mother and his own birth. She taught him the greatest lesson in giving thanks and finding contentment. "I remember her as she sat at the kitchen table in our house; the hard, old, brown hands folded across her starched apron, the glistening eyes, and the husky old whispering voice, saying, 'Much obliged, Lord, for my vittles.' 'Anna,' I asked, 'what's a vittle?' 'It's what I've got to eat and drink, that's vittles.' 'But you'd get your vittles whether you thanked the Lord or not.' 'Sure, but it makes everything taste better to be thankful.'" (Illustrations Unlimited)
