Now, if we think deeply upon this question, we shall gradually come to see that this expansive quality is to be found in the doctrine of the Atonement. It meets all the needs of our spiritual nature in a way that no other theory does, and responds to every stage of our progress. There is only one thing that will prevent it working, and that is, saying that we have no need of it. That is why St. John said, that if we say we have no sin, we deceive ourselves, and the truth is not in us (1 John i, 8). But the more we come into the light of Truth, and realize that sin is everything that is not in accordance with the Law of our own essential being as related to the Eternal Life, the more we shall see, not only that we have transgressed the Law in the past, but also that even now we are very far from completely fulfiling it; and the more light we get the more clearly we shall see this to be the case. Therefore, whatever may be the stage of our mental development, the assurance which we all need for the basis of our new life is that of the removal of sin--the sins of the past, and the daily errors of the present. We may form various theories, each to our own satisfaction, as to _how_ this takes place. For instance we may argue that, since "the Word" is the undifferentiated potential of Humanity, every human soul is included in the Self-offering of Christ, and that in Him we ourselves suffered on the Cross. Or we may say that our confession that such an offering is needed amounts to our participation in it. Or we may say with St. Paul that, as in Adam all are sinners, so in Christ all are made free from sin (1 Cor. xv, 22). That is, taking Adam and Christ as the representatives of two orders of men. Or we may fall back on the statement "Sacrifice and burnt offerings Thou wouldst not" (Ps. xl, 6), and on Jesus' own explanation of his death, that He offered himself in testimony to the Truth--that is, that the Eternal Life will no more exercise a retrospective vengeance upon us for our past misunderstanding of It, than would electricity or any other force. We may explain the _modus operandi_ of the great offering in any of these ways, for the Scripture presents it in all of them--but the great thing is to accept it; for by the nature of our mental constitution, such an acceptance, whether with or without an intellectual explanation, affords the assurance which we stand in need of; and building upon the Foundation we can safely rear the edifice of our future development.
