Luke 17:11-19

11Now on his way to Jerusalem, Jesus travelled along the border between Samaria and Galilee. 12As he was going into a village, ten men who had leprosy met him. They stood at a distance 13and called out in a loud voice, "Jesus, Master, have pity on us!" 14When he saw them, he said, "Go, show yourselves to the priests." And as they went, they were cleansed. 

15One of them, when he saw he was healed, came back, praising God in a loud voice. 16He threw himself at Jesus' feet and thanked him-and he was a Samaritan. 17Jesus asked, "Were not all ten cleansed? Where are the other nine? 18Was no one found to return and give praise to God except this foreigner?" 19Then he said to him, "Rise and go; your faith has made you well."

Hebrews 12:28

28Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe.

Colossians 3:15-17

15Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful. 16Let 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. 17And 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.

1 Thessalonians 5:18

18give thanks in all circumstances, for this is God's will for you in Christ Jesus.
