May the Lord bless you and yours as you gather for Thanksgiving this week. For 80 years we have been celebrating the fourth Thursday of November as Thanksgiving. As has been suggested, God calls us to be thankful every day. There are many verses one can find with your friend Mr. Google. I really like 1 Th. 5:16-18, "Rejoice always, pray continually, give thanks in all circumstances; for this is God's will for you in Christ Jesus."
Blessed Thanksgiving, and praying for each of you to experience the everyday blessings of God this week and always!
