The Atonement of the Lord Jesus Christ is the heart and core and center of revealed religion.

Elder Bruce R. McConkie Christ and the Creation

[The] testing of our limits in . . . service is made necessary by God’s plan to qualify His children to live with Him again forever. Heavenly Father loves His children. He offered us eternal life, to live with Him again in families and in glory forever.

To qualify us to receive that gift, He gave us a mortal body, the opportunity to be tempted to sin, and a way to be cleansed from that sin and to rise in the First Resurrection. He gave us His Beloved Son, Jehovah, as our Savior to make that possible.

The Savior was born in mortal life, was tempted but never sinned, and then in Gethsemane and on Golgotha paid the price of our sins so that we could be cleansed.

The purifying can come only to those who have faith enough in Jesus Christ to repent of sin, be cleansed through the ordinance of baptism, and make and keep covenants to obey all His commandments. And there was to be a fierce enemy of our souls, Lucifer, who would with his legions relentlessly try to capture every child of God to keep him or her from having the joy of eternal life.

Now, two millennia later, though we don’t know all the details pertaining to His birth, we certainly understand the unique parentage of this Babe of Bethlehem. We declare solemnly and with conviction: Jesus was born of an immortal Father and a mortal mother. From His immortal Father, Jesus inherited the power to live forever. From His mortal mother He inherited the fate of physical death.

Those unique attributes were essential for His mission to atone for the sins of all mankind. Thus Jesus the Christ was born to die (see 3 Nephi 27:13–15). He died that we might live. He was born that all humankind could live beyond the grave. His Atonement was wrought in Gethsemane—where He sweat great drops of blood—and on Golgotha, or Calvary, where His body was lifted up upon a cross above the place of the skull, which signified death.

This infinite Atonement would release man from the infinitude of death (see 2 Nephi 9:7). His Atonement made the Resurrection a reality and the gift of eternal life a possibility for all who would obey His teachings. His Atonement became the central act of all human history.

Our recollections of Christmas are enriched by these realities. Each one of us with a testimony of the Lord has the privilege in faith to know of His divine parentage and to testify that Jesus is the Son of the living God.

Jesus descended below all things in order to rise above all things. He expects us to follow His example. Yoked with Him, we can rise above all challenges, no matter how difficult they may be (see Matthew 11:29–30).

This is a re-post of a fundamental building block of doctrine concerning the Atonement.

If there had been no atonement of Christ, there would be no resurrection, no breaking of the bands of death, no coming forth from the grave.

If there had been no atonement, there would be no remission of sins; no return to the presence of God; no salvation of any sort, kind, or nature; no eternal life; no exaltation; no continuation of the family unit in eternity.

If there were no atonement of Christ, all men would be subject to “that awful monster the devil, and death, and hell, and that lake of fire and brimstone, which is endless torment” (2 Nephi 9:19).

If there were no atonement of Christ, “our spirits” would have become “like unto” Lucifer’s, “and we become devils, angels to a devil, to be shut out from the presence of our God, and to remain with the father of lies, in misery, like unto himself” (2 Nephi 9:9).

If there were no atonement of Christ, all men would be damned everlastingly, all would be sons of perdition, and the whole purpose of God and his eternal plan of salvation would utterly fail.

All things center in, revolve around, are anchored to, and are built upon the atoning sacrifice of the Lord Jesus Christ. There is no language given to men or angels to proclaim these truths with the power and verity and dignity that should attend them. Let it be blazoned in burning fire through all the sidereal heavens that salvation is in Christ and comes because of his atoning sacrifice.

After the death of his wife, American poet Henry Wadsworth Longfellow went into a long depression.  For a period of three years, he was unable to write.

Following is the poem that brought him out of his despondency:

TELL me not, in mournful numbers,
Life is but an empty dream!—
For the soul is dead that slumbers,
And things are not what they seem.

Life is real! Life is earnest!
And the grave is not its goal;
Dust thou art, to dust returnest,
Was not spoken of the soul.

Not enjoyment, and not sorrow,
Is our destined end or way;
But to act, that each to-morrow
Find us farther than to-day.

Art is long, and Time is fleeting,
And our hearts, though stout and brave,
Still, like muffled drums, are beating
Funeral marches to the grave.

In the world’s broad field of battle,
In the bivouac of Life,
Be not like dumb, driven cattle!
Be a hero in the strife!

Trust no Future, howe’er pleasant!
Let the dead Past bury its dead!
Act,—act in the living Present!
Heart within, and God o’erhead!

Lives of great men all remind us
We can make our lives sublime,
And, departing, leave behind us
Footprints on the sands of time;

Footprints, that perhaps another,
Sailing o’er life’s solemn main,
A forlorn and shipwrecked brother,
Seeing, shall take heart again.

Let us, then, be up and doing,
With a heart for any fate;
Still achieving, still pursuing,
Learn to labor and to wait.

Henry Wadsworth Longfellow
A Psalm of Life

The work of the Lord is a work of salvation. For whom? Through the grace of our Eternal Father and without any effort on the part of the beneficiaries, the atoning sacrifice of the Son of God has made it possible for all to rise from the dead. And beyond this, by virtue of that divine sacrifice, and through His grace and goodness, opportunities for eternal life may be opened to all through personal or vicarious service.

I think we must never lose sight of our Father’s transcendent declaration: “For behold, this is my work and my glory-to bring to pass the immortality and eternal life of man” (Moses 1:39).

When all is said and done, this is the purpose of our being, to assist our Father in the accomplishment of His work and His glory. For this reason He sent His Son into the world to take upon himself the sins of the world, to offer his life in a wondrous atonement for those sins, to suffer and die upon the cross in a supreme sacrifice for the blessing of all mankind, to come forth triumphant from the tomb as the master of life and death, of mortality and immortality.

What was it that suddenly changed these disciples to confident, fearless, heroic preachers of the gospel of Jesus Christ? It was the revelation that Christ had risen from the grave. His promises had been kept, his Messianic mission fulfilled. In the words of one universal writer, “The final and absolute seal of genuineness had been put on all his claims, and the indelible stamp of a divine authority upon all his teachings. The gloom of death had been banished by the glorious light of the presence of their risen, glorified Lord and Savior.”

On the evidence of these unprejudiced, unexpectant, incredulous witnesses, faith in the resurrection has its impregnable foundation.

The fundamental principles of our religion are the testimony of the Apostles and Prophets, concerning Jesus Christ, that He died, was buried, and rose again the third day, and ascended into heaven; and all other things which pertain to our religion are only appendages to it.

Joseph Smith
Teachings of the Prophet Joseph Smith, sel. Joseph Fielding Smith [1938], 121

I feel in myself the future lie. I am like a forest once cut down; the new shoots are stronger than ever. I am rising, I know, toward the sky. The sunshine is on my head. The earth gives me its generous sap, but heaven lights me with the reflection of unknown worlds.

You say the soul is nothing but the resultant of the bodily powers. Why then is my soul more luminous when my bodily powers begin to fail? The nearer I approach the end, the plainer I hear around me the immortal symphonies of the worlds which invite me. It is marvelous yet simple. It is a fairy tale, and it is history.

When I go down to the grave I can say, like so many others, I have finished my life. My day’s work will begin the next morning. My tomb is not a blind alley. It is a thoroughfare. It closes in the twilight to open in the dawn.

There was only one way of redemption, one way in which reparation could be made and the body restored again to the spirit; that was by an infinite atonement, and it had to be made by an infinite being, someone not subject to death and yet someone who had the power to die and who also had power over death. And so our Father in heaven sent us his Son, Jesus Christ, into the world with life in himself. And because he had a mother who had blood in her veins he had the power to die. He could yield up his body to death and then take it again. Let me read his own words: “Therefore doth my Father love me, because I lay down my life, that I might take it again.

“No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.” (John 10:17-18.)

He had power to lay down his life, and on the cross he paid the price for our sins and at the same time for Adam’s transgression. His infinite atonement resulted in two things: (l) restoration of the body to the spirit, and (2) the redemption of those who accept the gospel of Jesus Christ and who will be loyal in the keeping of his commandments-freedom from their sins.

Now, in conclusion, what are we going to do? Are we going to love him? Are we going to realize the great work he did for us and are we going to be grateful, or are we going to violate his commandments? I would like to read something by Sydney Harris, taken from the Deseret News in 1964, entitled “Would We Believe and Follow?”

“If there should be a second coming, would there not be soon a second crucifixion? And this time, not by the Romans or the Jews, but by those who proudly call themselves Christians? I wonder! I wonder how we today would regard and treat this man with his strange and frightening and ‘impractical’ doctrines of human behavior and relationships. Would we believe and follow, any more than the masses of people in his day believed and followed?

“Would not the militarists among us assail him as a cowardly pacifist because he urges us not to resist evil?

“Would not the nationalists among us attack him as a dangerous internationalist because he tells us we are all of one flesh?

“Would not the wealthy among us castigate him as a trouble-making radical because he bars the rich from entering the kingdom of heaven?

“Would not the liberals among us dismiss him as a dreamy vagabond because he advises us to take no thought for the morrow, to lay up no treasures on earth?

“Would not the ecclesiastics among us denounce him as a ranting heretic because he cuts through the core of ritual and commands us only to love God and our neighbors?

“Would not the sentimentalist among us deride him as a cynic because he warns us that the way to salvation is narrow and difficult?

“Would not the puritans among us despise and reject him because he eats and drinks with the publicans and sinners, preferring the company of winebibbers and harlots to that of ‘respectable’ church members?

“Would not the sensual among us scorn him because he fasts for forty days in the desert, neglecting the needs of the body?

“Would not the proud and important among us laugh at him when he instructs the twelve disciples that he who would be ‘first’ should be the one to take the role of the least and serve all?

“Would not the worldly wise and educated among us be aghast to hear that we cannot be saved except we become as children, and that a little child shall lead us?

“Would not each of us-in his own way-find some part of this man’s saying and doing to be so threatening to our ways of life, so much at odds with our rooted beliefs, that we could not tolerate him for long?

“I wonder, I wonder if we are any more prepared for the second coming than we would have been for the first.”
