"Because He was God-even the Son of God-He could carry the weight and burden of other men's sins on Himself. Isaiah prophesied our Savior's willingness to do this in these words: 'Surely he has borne our griefs, and carried our sorrows. He was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.' (Isaiah 53:4-5.)
"That holy, unselfish act of voluntarily taking on Himself the sins of all other men is called the Atonement. How one could bear the sins for all is beyond the comprehension of mortal man. But this I know: He did take on Himself the sins of all and did so out of His infinite love for each of us." (Teachings of Ezra Taft Benson, p.14-15)
