Selection from Arcana Coelestia ~ Emanuel Swedenborg
The Lord Himself sanctified Himself to the Divine, that is, united His Human to His Divine by the combats and victories of temptations.
It is a common belief at this day that the burnt-offerings and sacrifices signified the Lord's passion, and that by this the Lord made expiation for the iniquities of all; indeed, that He took them upon Himself, and thus bore them; and that those who believe are in this manner justified and saved, provided they think, even though it were in the last hour before death, that the Lord suffered for them, no matter how they may have lived during the whole course of their life.But the case is not really so:
The passion of the cross was the extremity of the Lord's temptation, by which He fully united His Human to His Divine and His Divine to His Human, and thus glorified Himself. This very union is the means by which those who have the faith in Him which is the faith of charity, can be saved. For the supreme Divine Itself could no longer reach to the human race, which had removed itself so far from the celestial things of love and the spiritual things of faith, that men no longer even acknowledged them, and still less perceived them. In order therefore that the supreme Divine might be able to come down to man in such a state, the Lord came into the world and united His Human to the Divine in Himself; which union could not be effected otherwise than by the most grievous combats of temptations and by victories, and at length by the last, which was that of the cross.Hence it is that the Lord can from His Divine Human illumine minds, even those far removed from the celestial things of love, provided they are in the faith of charity. For the Lord in the other life appears to the celestial angels as a Sun, and to the spiritual as a Moon, whence comes all the light of heaven. This light of heaven is of such a nature that when it illumines the sight of spirits and angels, it also illumines their understanding at the same time.
This is inherent in that light, so that in heaven so much as anyone has of external light, so much has he of internal light, that is, so much of understanding; which shows wherein the light of heaven differs from the light of the world.
It is the Lord's Divine Human which illuminates both the sight and the understanding of the spiritual; which would not take place if the Lord had not united His Human Essence to His Divine Essence; and if He had not united them, man in the world would no longer have had any capacity of understanding and perceiving what is good and true, nor indeed would a spiritual angel in heaven have had any; so that they would have had nothing of blessedness and happiness, consequently nothing of salvation.From this we can see that the human race could not have been saved unless the Lord had assumed the Human and glorified it.
Hence then anyone may infer what truth there is in the idea that men are saved if they only think from a kind of interior emotion that the Lord suffered for them, and took away their sins, however they may have lived; whereas the light of heaven from the Lord's Divine Human cannot reach to any but those who live in the good of faith, that is, in charity; or what is the same, those who have conscience. The very plane into which that light can operate, or the receptacle of that light, is the good of faith, or charity, and thus conscience.
