good morning.
as americans gather to celebrate this week, we show our gratitude for the many blessings in our lives. we are grateful for our friends and families who fill our lives with purpose and love. we're grateful for our beautiful country, and for the prosperity we enjoy. we're grateful for the chance to live, work and worship in freedom. and in this thanksgiving week, we offer thanks and praise to the provider of all these gifts, almighty god.
we also recognize our duty to share our blessings with the least among us. throughout the holiday season, schools, churches, synagogues and other generous organizations gather food and clothing for their neighbors in need. many young people give part of their holiday to volunteer at homeleshelters or food pantries. on thanksgiving, and on every day of the year, america is a more hopeful nation because of the volunteers who serve the weak and the vulnerable.
the thanksgiving tradition of compassion and humility dates back to the earliest days of our society. and through the years, our deepest gratitude has often been inspired by the most difficult times. almost four centuries ago, the pilgrims set aside time to thank god after suffering through a bitter winter. george washington held thanksgiving during a trying stay at valley forge. and president lincoln revived the thanksgiving tradition in the midst of a civil war.
the past year has brought many challenges to our nation, and americans have met every one with energy, optimism and faith. after lifting our economy from a recession, manufacturers and entrepreneurs are creating jobs again. volunteers from acrothe country came together to help hurricane victims rebuild. and when the children of beslan, russia suffered a brutal terrorist attack, the world saw america's generous heart in an outpouring of compassion and relief.
the greatest challenges of our time have come to the men and women who protect our nation. we're fortunate to have dedicated firefighters and police officers to keep our streets safe. we're grateful for the homeland security and intelligence personnel who spend long hours on faithful watch. and we give thanks to the men and women of our military who are serving with courage and skill, and ma-ki-ng our entire nation proud.12
