These are all great verses, and I love your idea. Thanksgiving is a time to not only give thanks for all the blessings God has given us, it is a time for me to focus on the foundation of Thanksgiving, our gracious and loving God. Psalm 100 is titled as A Psalm of Thanksgiving, and the spotlight is placed on the Lord:
Psalm 100
New King James Version
A Song of Praise for the Lord’s Faithfulness to His People
A Psalm of Thanksgiving.
1 Make a joyful shout to the
Lord, all you lands!
2 Serve the Lord with gladness;
Come before His presence with
singing.
3 Know that the Lord, He is God;
It is He who has made us, and
not we ourselves;
We are His people and the
sheep of His pasture.
4 Enter into His gates with
thanksgiving,
And into His courts with
praise.
Be thankful to Him, and bless
His name.
5 For the Lord is good;
His mercy is everlasting,
And His truth endures to all
generations.
Let's join the host of heaven who are also thankful to our awesome and wonderful God!
Amen! Blessing and glory and
wisdom,
Thanksgiving and honor and
power and might,
Be to our God forever and ever.
Amen. (Rev. 7:12)
