"“I lay down My life, that I might take it again. No man taketh it from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again.” While as a member of the human family He was mortal, as God He was the fountain of life for the world. He could have withstood the advances of death, and refused to come under its dominion; but voluntarily He laid down His life, that He might bring life and immortality to light. He bore the sin of the world, endured its curse, yielded up His life as a sacrifice, that men might not eternally die. “Surely He hath 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. All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on Him the iniquity of us all.” Isaiah 53:4-6 . DA 484.1"
"Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. But 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. All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all."
Ellen White directly references Isaiah 53:4-6 in this passage.
