The Lord, in His essence, is infinite. He is the source of all energy, the well-spring of reality itself. His love is of such power that we would be destroyed by its direct heat, which is infinitely greater than the heat of the finite sun. His wisdom, the direct outpouring of His love, is of such power that we would be blinded by its brightness, which is infinitely brighter than the light of the finite sun. His immensity – which is beyond immensity – is inaccessible to our finite imaginative powers. In His essence, He is unknowable to us.

Yet we know Him. How? The Writings say that His love and wisdom project as a human form, then pass through that form almost like a filter to come to us as divine truth. That truth is like a container that is conformed to our minds, enough that we can hang onto an idea of the Lord and receive His love. We can have ideas that are filled with the Lord, and feel like we know Him, though really what we know is just the amount we can handle.

That divine truth is, itself, "the only begotten son." It was the son as the soul within the physical man Jesus; it was the son as the inner meaning of the Old Testament; it was the son as expressed by the Lord in other ways before Moses, and it is still the son now as the inner meaning of the Old and New Testaments together. It knows the Father – the love that is the Lord’s essence – and does, in fact, declare the Father to us, if only we will listen.

222. "'As I also overcame and sit with My Father on His throne.'" This symbolically means, as He and the Father are one and constitute heaven.

That the Father and the Lord are one is something we showed fully in The Doctrine of the New Jerusalem Regarding the Lord. And elsewhere we have shown that heaven is not heaven in consequence of the angels' own qualities, but owing to the Lord's Divinity that is present in the angels and among them. Therefore the statement, "as I sit with My Father on His throne," symbolically means, as He and the Father are one and constitute heaven. The throne is heaven (nos. 14, 221).

"As I also overcame" means, symbolically, that through the temptations or trials that His human nature suffered, and through the last of them which was His suffering of the cross, as well as by His fulfilling all things of the Word, the Lord overcame the hells and glorified His humanity, which is to say that He united it to His Divinity that He had within Him from conception, which is called Jehovah, the Father. (Concerning this, see The Doctrine of the New Jerusalem Regarding the Lord, nos. 8-11 12-14, 29-36, and also no. 67 above.)

[2] The Lord says, "To him who overcomes I will grant to sit with Me on My throne, as I also overcame and sit with My Father on His throne," and He says this because the Lord's union with the Father, that is to say, with His Divinity within Him, had as a goal to make it possible for a person to be conjoined with the Divinity in the Lord called the Father. That is because it is impossible for a person to be conjoined with the Divinity of the Father directly, but is possible indirectly through His Divine humanity, which is Divinely natural. Therefore the Lord says,

No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has exhibited Him. (John 1:18)

And in another place,

I am the way, the truth, and the life. No one comes to the Father except through Me. (John 14:6)

The Lord's conjunction with a person takes place through His Divine truth, and this truth is the Lord's in the person, thus the Lord, and is not at all the person's, thus is not the person. The person indeed feels it to be his own, and yet it is not his, for it does not become one with him, but is only an adjunct to him. It is otherwise with the Divinity of the Father. This is not an adjunct to the Lord's humanity but united with it, as the soul is with its body.

Whoever understands this can understand the following declarations by the Lord:

He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. (John 15:4-5)

On that day you will know that I am in My Father, and you in Me, and I in you. (John 14:20)

And this:

Sanctify them in Your truth. Your word is truth... For their sakes I sanctify Myself, that they also may be sanctified in the truth..., that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us..., I in them, and You in Me. (John 17:17, 19, 21, 23)
