Psalm 100
Shout for joy to the LORD, all the earth. 2 Worship the LORD with gladness; come before Him with joyful songs. 3 Know that the LORD is God. It is He who made us, and we are His; we are His people, the sheep of His pasture. 4 Enter His gates with thanksgiving and His courts with praise; give thanks to Him and praise His name. 5 For the LORD is good and His love endures forever; His faithfulness continues through all generations.

1 Thessalonians 5:18
Give thanks in all circumstances; for this is God’s will for you in Christ Jesus.

Ephesians 5:20
Always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ.
