Atonement of Jesus Christ
As used in the scriptures, to atone is to suffer the penalty for sins, thereby removing the effects of sin from the repentant sinner and allowing him or her to be reconciled to God. Jesus Christ was the only one capable of carrying out the Atonement for all mankind. Because of His Atonement, all people will be resurrected, and those who obey His gospel will receive the gift of eternal life with God.
As descendants of Adam and Eve, all people inherit the effects of the Fall. In our fallen state, we are subject to opposition and temptation. When we give in to temptation, we are alienated from God, and if we continue in sin, we experience spiritual death, being separated from His presence. We are all subject to temporal death, which is the death of the physical body
The only way for us to be saved is for someone else to rescue us. We need someone who can satisfy the demands of justice—standing in our place to assume the burden of the Fall and to pay the price for our sins. Jesus Christ has always been the only one capable of making such a sacrifice.
From before the Creation of the earth, the Savior has been our only hope for "peace in this world, and eternal life in the world to come".
Only He had the power to lay down His life and take it up again. From His mortal mother, Mary, He inherited the ability to die. From His immortal Father, He inherited the power to overcome death. He declared, "As the Father hath life in himself; so hath he given to the Son to have life in himself" (John 5:26).
Only He could redeem us from our sins. God the Father gave Him this power. The Savior was able to receive this power and carry out the Atonement because He kept Himself free from sin: "He suffered temptations but gave no heed unto them". Having lived a perfect, sinless life, He was free from the demands of justice. Because He had the power of redemption and because He had no debt to justice, he could pay the debt for those who repent.
Jesus's atoning sacrifice took place in the Garden of Gethsemane and on the cross at Calvary. In Gethsemane He submitted to the will of the Father and began to take upon Himself the sins of all people. He has revealed some of what He experienced as He paid the price for our sins:
"I, God, have suffered these things for all, that they might not suffer if they would repent;
"But if they would not repent they must suffer even as I;
"Which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit—and would that I might not drink the bitter cup, and shrink—
"Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men"
The Savior continued to suffer for our sins when He allowed Himself to be crucified—"lifted up upon the cross and slain for the sins of the world"
On the cross, He allowed Himself to die. His body was then laid in a tomb until He was resurrected and became "the firstfruits of them that slept" (1 Corinthians 15:20). Through His death and Resurrection, He overcame physical death for us all.
Jesus Christ redeems all people from the effects of the Fall. All people who have ever lived on the earth and who ever will live on the earth will be resurrected and brought back into the presence of God to be judged. Through the Savior's gift of mercy and redeeming grace, we will all receive the gift of immortality and live forever in glorified, resurrected bodies.
Although we are redeemed unconditionally from the universal effects of the Fall, we are accountable for our own sins. But we can be forgiven and cleansed from the stain of sin if we "apply the atoning blood of Christ". We must exercise faith in Jesus Christ, repent, be baptized for the remission of sins, and receive the gift of the Holy Ghost.
