Elder Richard G Scott, He Lives! All Glory to His Name, April 2010 General Conference

Without the Atonement, Father in Heaven’s plan of happiness could not have been placed fully into effect. The Atonement gives all the opportunity to overcome the consequences of mistakes made in life. When we obey a law, we receive a blessing. When we break a law, there is nothing left over from prior obedience to satisfy the demands of justice for that broken law. The Savior’s Atonement permits us to repent of any disobedience and thereby avoid the penalties that justice would have imposed.
