2818. To slay his son. That this signifies until whatever was from the merely human was dead, is evident from the internal sense of these words; for they signify the Lord’s most grievous and inmost temptations, the last of which was that of the cross, in which it is evident that what was merely human also died. This could not be represented by Abraham’s son or Isaac, because to sacrifice sons was an abomination; but it was represented so far as it could be, namely, even to the attempt, but not to the act. Hence it is evident that by these words, “Abraham took the knife to slay his son,” is signified until all that was merely human was dead.

[2] That it was known from the most ancient time that the Lord was to come into the world, and was to suffer death, is evident from the fact that the custom prevailed among the Gentiles of sacrificing their sons, believing that they were thus purified, and propitiated to God; in which abominable custom they could not have placed their most important religious observance, unless they had learned from the ancients that the Son of God was to come, who would, as they believed, be made a sacrifice. To this abomination even the sons of Israel were inclined, and Abraham also; for no one is tempted except by that to which he is inclined. That the sons of Jacob were so inclined is evident in the Prophets; but lest they should rush into that abomination, it was permitted to institute burnt-offerings and sacrifices (see n. 922, 1128, 1241, 1343, 2180).

227. As it is desirable that the origin of perception, internal dictate, and conscience, should be known, and as at the present day it is altogether unknown, I may relate something on the subject. It is a great truth that man is governed by the Lord by means of spirits and angels. When evil spirits begin to rule, the angels labor to avert evils and falsities, and hence arises a combat. It is this combat of which the man is rendered sensible by perception, dictate, and conscience. By these, and also by temptations, a man might clearly see that spirits and angels are with him, were he not so deeply immersed in corporeal things as to believe nothing that is said about spirits and angels. Such persons, even if they were to feel these combats hundreds of times, would still say that they are imaginary, and the effect of a disordered mind. I have been permitted to feel such combats, and to have a vivid sense of them, thousands and thousands of times, and this almost constantly for several years, as well as to know who, what, and where they were that caused them, when they came, and when they departed; and I have conversed with them.
