Sometimes the Course talks about what you can do for yourself, in terms of receiving your own healing and having your mind corrected so that sickness can be healed.
"Atonement heals with certainty, and cures all sickness. For the mind which understands that sickness can be nothing but a dream is not deceived by forms the dream may take. Sickness where guilt is absent cannot come, for it is but another form of guilt. Atonement does not heal the sick, for that is not a cure. It takes away the guilt that makes the sickness possible. And that is cure indeed. For sickness now is gone, with nothing left to which it can return."
And sometimes the Course talks about how you can use your new-found healed state of mind to help others, as expressions of the love that you have become willing to accept as true. That part of the Course is often overlooked and frowned upon as though it is too radical and supernatural to believe.
"Miracles occur naturally as expressions of love." - note that miracles express LOVE once you have become willing to receive love for yourself. What are you going to do with the love when you've got it?
"The miracle is an expression of an inner awareness of Christ and the acceptance of His Atonement." - note that miracles express Christ BECAUSE of your awareness of the atonement.
"A miracle is a universal blessing from God through me to all my brothers." - note that miracles bless ALL of your brothers!
"Miracles are natural signs of forgiveness. Through miracles you accept God's forgiveness by extending it to others." - note that miracles are extended to others and they are "signs" of forgiveness - manifestations coming from a forgiven/forgiving mind.
"I [Jesus] inspire all miracles which are intercessions. They intercede for your holiness." - note that Jesus is saying He performs miracles on your behalf!
Believing that the Course is only talking along one line and not two leads to the belief that you should "only" work on your own healing. There is truth in it. And the Course speaks to it on many occasions. BUT... there is also more to this than just this one part of the Course. There is a second part which is in the working of miracles for the benefit of others, directly healing them and alleviating them of suffering.
When the Course says that "it is the privilege of the forgiven to forgive", what it is saying is, once you become able to see yourself as forgiven, through accepting the atonement, you then actually receive the "privilege" of being able to bestow forgiveness on others. That means, YOU CAN UNDO OTHER PEOPLE'S SINS. And that means you can give them miraculous cures. You become an authority, you gain access to the power of love, and you become able to EXPRESS the love that you've received.
The Course isn't all about just what you can do for yourself. It's also about what you can do for your brother as well.
