3736. And I return in peace to my father's house. That this signifies even to perfect union, is evident from the fact that the "house of my father," when predicated of the Lord, is the Divine Itself in which the Lord was from His very conception; and to "return to that house," is to return to the Divine good itself which is called the "Father." That this good is the "Father" may be seen above (n. 3704); and that to "return to that house" is to be united, is evident. The same was meant by the Lord when He said that He came forth from the Father and was come into the world, and that again He should go to the Father; that is to say, by coming forth from the Father" is meant that the Divine Itself assumed the Human; by "coming into the world," that He was as a man; and by His "going again to the Father," that He would unite the Human Essence to the Divine Essence. The same was meant also by these words of the Lord in John:
If ye should see the Son of man ascending where He was before (John 6:62).
Jesus knowing that the Father had given all things into His hands, and that He came forth from God, and went to God, said unto them, Children, yet a little while I am with you; whither I go ye cannot come (John 13:3, 33).
Now I go unto Him that sent Me; and none of you asketh Me, Whither goest Thou? It is expedient for you that I go away; for if I go not away the Comforter will not come unto you; but if I go I will send Him unto you. A little while and ye shall not see Me; and again a little while and ye shall see Me; and because I go to the Father (John 16:5, 7, 16-17).
I came out from the Father, and am come into the world; again I leave the world, and go to the Father (John 16:28).
In these passages, to "go to the Father" is to unite the Human Essence to the Divine Essence.
