In the atonement, you gain the authority to forgive the sins of others, and not just your own sins.
This literally means you are able to heal others instantly through your forgiveness, because forgiveness leads to an authority over illusions.
It's not just a technicality, like you accept the atonement and you're done. The atonement puts you in the hot seat. It gives you the power of God. It empowers you with commanding authority. And what you then say, goes.
Claiming the atonement for yourself will grant you the ability to give the atonement to others. And that means the undoing of all signs and symptoms of separation, including the reversal of death.
Raising of the dead would not be possible if it had to mean that the other person somehow had to do something on their own in order to resurrect. Yet Jesus raised the dead, and others have also. The dead cannot raise themselves.
This demonstrates to you the miraculous power that the atonement offers you. The power to overcome all illusions for yourself AND for others. And if it be God's will, you too can restore your brother to life.
He who shares the authority of God knows no limitations. Unlock the key to salvation and open the door to the atonement, and you will step through Heaven's gates. And from there, the atonement of yourself and of the whole world is complete in your eyes. And now have dominion over all suffering and death.
