"The things we hold sacred unite us and transcend distance, time, and even the constraints of a pandemic: faith, family, and friendship; a love of the arts, learning, and nature; gratitude, service, and community; unity and peace. These are the gifts that tie together the heart strings of our lives. These are the Gifts from the Heart," President Joe Biden and first lady Jill Biden wrote in a welcome letter at the beginning of the commemorative 2021 White House Holiday Guide.
