Former President Jimmy Carter, who turned 100 on Sunday, was known for his strong faith and his ability to connect his Christian beliefs to his policy pursuits. Carter's faith played a significant role in his foreign policy achievements, including the 1978 peace deal between Egypt and Israel. He described himself as a 'born-again Christian' during his 1976 presidential campaign, which was unusual at the time and made him a curiosity to many. Carter used his presidency to champion human rights, environmental conservation, and peace, and he continued his work through The Carter Center after leaving office. He was an outlier in the Democratic Party with his unabashed evangelism and his progressive stances on various issues.
