Jesus Christ: His Atoning Sacrifice

"The atoning sacrifice had to be carried out by the sinless Son of God, for fallen man could not atone for his own sins. The Atonement had to be infinite and eternal―to cover all men throughout all eternity."

See the complete discourse: "The Miracle of the Atonement," by Elder Scott Grow, April 2011 General Conference
