If the only prayer you said in your whole life was, "thank you," that would suffice.
We do not celebrate Thanksgiving in Australia although each and everyone of us can offer gratitude for what we have been blessed with and be truly thankful, always.
Enjoy Your Thanksgiving Day My Friends.
Our rural ancestors, with little blest,
Patient of labour when the end was rest,
Indulged the day that housed their annual grain,
With feasts, and off'rings, and a thankful strain.
