President Joseph Fielding Smith

Justice made certain demands, and Adam could not pay the price, so mercy steps in. The Son of God says: "I will go down and pay the price. I will be the Redeemer and redeem men from Adam's transgression. I will take upon me the sins of the world and redeem or save every soul from his own sins who will repent." That is the only condition. The Savior does not save anybody from his individual sins only on condition of his repentance. So the effect of Adam's transgression was to place all of us in the pit with him. Then the Savior comes along, not subject to that pit, and lowers the ladder. He comes down into the pit and makes it possible for us to use the ladder to escape. . . .

This was precisely the condition that Adam placed himself and his posterity in, when he partook of the forbidden fruit. All being together in the pit, none could gain the surface and relieve the others. The pit was banishment from the presence of the Lord and temporal death, the dissolution of the body. And all being subject to death, none could provide the means of escape.

Therefore, in his infinite mercy, the Father heard the cries of his children and sent his Only Begotten Son, who was not subject to death nor to sin, to provide the means of escape. This he did through his infinite atonement and the everlasting gospel.
