While the nation honors the life of Jimmy Carter on Thursday, President Joe Biden and First Lady Jill Biden looked back on the former president's partnership with his wife Rosalynn Carter, calling it "a love story for the ages.

Former President Jimmy Carter, who will be laid to rest in a Jan. 9 funeral, and Rosalynn Carter fell in love, raised a family and spent most of their 77 years of marriage living in Plains, Ga.

The 39th president, who died Sunday, and the former first lady set the record for longest presidential marriage.

Sharing scripture connected the Carters—the longest-married presidential couple in U.S. history—even when they were miles apart.

Jimmy Carter—the 39th president of the United States, who died on Dec. 29 at 100—was laid to rest at the Georgia home he shared with wife Rosalynn Carter.

President Jimmy Carter’s legacy of giving back endures in several nonprofits through which he and his wife, Rosalynn Carter, worked in the almost 50 years after they left the White House.

They had four children: Jack, Chip, Jeff, and Amy. The Carters have 25 grandchildren and great-grandchildren, The Carter Center said in a statement following Rosalynn's death. Their oldest son, 77-year-old John William "Jack" Carter, followed his father into politics.

"My mom spent most of her life in love with my dad," Amy says in a video shared by President Joe Biden and First Lady Jill Biden

Looking back on Jimmy Carter's 100 years of life, a common theme is his love for his wife and how they inspired each other.

While former president Jimmy Carter certainly left his mark on America as the 39th president of the United States, one of his biggest legacies transcends the work of his presidential administration: his 77-year marriage to Rosalynn Carter.
