Most of us, most of the time, would probably have to sheepishly admit to the latter.
On this Thanksgiving Day, amidst the busyness of cooking and eating or traveling or visiting or watching football, take some time to sit down and write a thank-you note to God. List everything you can think of that you're thankful for in your life, and then tell God how you grateful you are for everything He has done for you.
You may then wish to pray the following prayer from The Catholic Prayer Book:
Thank you, Father, for having created us and given us to each other in the human family. Thank you for being with us in all our joys and sorrows, for your comfort in our sadness, your companionship in our loneliness. Thank you for yesterday, today, tomorrow and for the whole of our lives. Thank you for friends, for health and for grace. May we live this and every day conscious of all that has been given to us. Amen.
Wishing you a blessed Thanksgiving.
