The sin is not blotted out from Karma; but it can be blotted out from the Earth-evolution, and this it is that man cannot do because of the human weakness that results from the Luciferic temptation. Christ accomplishes this. With the remission of sins we are saved from the pain of having added an objective debt to the Earth-evolution for all eternity. […]
And he who deeply grasps Christ’s attitude towards sin and debt may speak thus: “Because man in the course of the Earth’s existence could not blot out his guilt for the whole Earth, a Cosmic Being had to descend in order that the Earth’s debt might be discharged.”
