Thankfulness is the Right Choice.

Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you. 1 Thessalonians 5:16-18 ESV

Oh give thanks to the Lord, for he is good, for his steadfast love endures forever! Ps. 107:1 ESV

Feeling gratitude and not expressing it is like wrapping a present and not giving it. 
William Arthur Ward

Let us come into his presence with thanksgiving; let us make a joyful noise to him with songs of praise! Psalm 95:2 ESV

And let the peace of Christ rule in your hearts, to which indeed you were called in one body. And be thankful. Colossians 3:15 ESV

THT: Nothing has the power to change your attitude like gratitude.

TA: Thankfulness is a Divine pathway to peace and contentment. (Like a key to a secret place)

Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God’s peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus. Phil. 4:6-7 MSG

Not only should we count our blessings, but we should make our blessings count.

Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God. And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. Colossians 3:16-17 ESV
