3736. 'And I come back in peace to my father's house' means even to the point of perfect union. This becomes clear from the fact that 'father's house', used in reference to the Lord, is the Divine itself which was the Lord's from actual conception. 'Coming back to that house' is resuming to Divine Good itself, which is called 'the Father' - Divine Good being 'the Father', see 3704. 'Coming back to that house' clearly means being united. The same was meant by the Lord when He said that He had come forth from the Father and had come into the world, and that He would be going again to the Father. That is to say, His coming forth from the Father means that the Divine itself had taken on the Human; His coming into the world means that He was as a human being; and His going again to the Father means that He would unite the Human Essence to the Divine Essence. This was the meaning of the following words spoken by the Lord in John,

What if you were to see the Son of Man ascending to where He was before? John 6:62.

In the same gospel,

Jesus knew that the Father had given all things into His hands and that He had come forth from God and was going to God. My children, yet a little while I am with you. Where I am going you cannot come. John 13:3, 33.

In the same gospel,

Now I am going away to Him who sent Me; but none of you asks Me, Where are you going away? It is to your advantage that I go away, for if I did not go away the Paraclete would not come to you; but if I go away I will send Him to you. A little while, and you will not see Me, and again a little while, and you will see Me [because I am going away to the Father. Some of His disciples said to one another, What is this that He says to us, A little while, and you will not see Me, and again a little while, and you will see Me,] and, Because I am going away to the Father? John 16:5, 7, 10, 16-17.

In the same gospel,

I came forth from the Father and have come into the world; again, I am leaving the world and going to the Father. John 16:28.

'Going away to the Father' in these places means uniting the Human Essence to the Divine Essence.
