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

You, perhaps, are among those troubled people. When you come face to face with yourself in those moments of quiet contemplation—that many of us try to avoid—are there some unsettled things that bother you?

Do you have something on your conscience? Are you still, to one degree or another, guilty of anything small or large?

We often try to solve guilt problems by telling one another that they don’t matter. But somehow, deep inside, we don’t believe one another. Nor do we believe ourselves if we say it. We know better. They do matter!

Our transgressions are all added to our account, and one day if it is not properly settled, each of us, like Belshazzar of Babylon, will be weighed in the balance and found wanting.

There is a Redeemer, a Mediator, who stands both willing and able to appease the demands of justice and extend mercy to those who are penitent, for “He offereth himself a sacrifice for sin, to answer the ends of the law, unto all those who have a broken heart and a contrite spirit; and unto none else can the ends of the law be answered.” (2 Ne. 2:7.)

Already He has accomplished the redemption of all mankind from mortal death; resurrection is extended to all without condition.

He also makes possible redemption from the second death, which is the spiritual death, which is separation from the presence of our Heavenly Father. This redemption can come only to those who are clean, for no unclean thing can dwell in the presence of God.

If justice decrees that we are not eligible because of our transgression, mercy provides a probation, a penitence, a preparation to enter in.

Elder Boyd K. Packer
The Mediator,” Ensign, May 1977, 54

For some reason, we think the Atonement of Christ applies only at the end of mortal life to redemption from the Fall, from spiritual death. It is much more than that. It is an ever-present power to call upon in everyday life. When we are racked or harrowed up or tormented by guilt or burdened with grief, He can heal us.

Elder Boyd K. Packer

The Touch of the Master’s Hand,” Ensign, May 2001, 22

[The Atonement of Christ] is the very root of Christian doctrine. You may know much about the gospel as it branches out from there, but if you only know the branches and those branches do not touch that root, if they have been cut free from that truth, there will be no life nor substance nor redemption in them.
