The Savior's Broken Heart and Contrite Spirit
"What are a broken heart and a contrite spirit? And why are they considered a sacrifice? "As in all things, the Savior's life offers us the perfect example: though Jesus of Nazareth was utterly without sin, He walked through life with a broken heart and a contrite spirit, as manifested by His submission to the will of the Father. 'For I came down from heaven, not to do mine own will, but the will of him that sent me' (John 6:38). To His disciples He said, 'Learn of me; for I am meek and lowly in heart' (Matthew 11:29). And when the time came to pay the ultimate sacrifice entailed in the Atonement, Christ shrank not to partake of the bitter cup but submitted completely to His Father's will."
