2 Nephi 9:19-22
O the greatness of the mercy of our God, the Holy One of Israel! For he delivereth his saints from that awful monster the devil, and death, and hell, and that lake of fire and brimstone, which is endless torment.
20 O how great the holiness of our God! For he knoweth all things, and there is not anything save he knows it.
21 And he cometh into the world that he may save all men if they will hearken unto his voice; for behold, he suffereth the pains of all men, yea, the pains of every living creature, both men, women, and children, who belong to the family of Adam.
22 And he suffereth this that the resurrection might pass upon all men, that all might stand before him at the great and judgment day.
Our Heavenly Father’s great plan of happiness required that his Only Begotten Son come into this world in human form to redeem us that we might be delivered from death and hell. Heavenly Father, who knoweth all things, knew that Jesus could and would do it – he would fulfil the task given him. The alternative was unthinkable – ‘death, and hell and that lake of fire and brimstone’ for all of the family of Adam.
But that was not all – He suffered also the ‘pains of all men’.
‘Thus we understand the Atonement has broader purpose than providing a means to overcome sin. This greatest of all earthly accomplishments gives the Savior the power to fulfill this promise: “If ye will turn to the Lord with full purpose of heart, and put your trust in him, and serve him with all diligence … , if ye do this, he will … deliver you out of bondage” (Mosiah 7:33).’ (Donald L Hallstrom, April 2010)
