Therefore do not be foolish, but understand what the Lord’s will is. Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit, speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ. -Ephesians 5:17-20
In Christian life, thankful is intended to be a way of life. It is not incidental that Paul advices us, no, charges us to be thankful in everything. The key to living a joyful is to choose to be thankful for the life that we have.
It is interesting that we live in such a properous nation, and in such lavish comfort over all, and yet most of us have a lot of trouble being thankful. Here nation is a testament to the truth that getting what we want does not make us happy. What makes us happy is recognizing that we already have more than we deserve.
God is a merciful and caring God, and even the most disadvantaged person in the world has still been given life, a gift that was unearned and was not owed him. My every breath is a gift. Even though it is easy to be frustrated that things are as good as they were, be grateful that you still eat three square meals a day, have a roof over your head, and clean clothes on your back, for there are many who don't have those things who are grateful for what we have.
So this Thanksgiving, give thanks. Know that God is with you and is blessing you. Look at your family and friends and thank God for them.
And one more thing: have fun! God loves a cheerful thanker.
