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.

2628. 'Abraham called the name of his son born to him' means the nature of the Rational was such that it was Divine. This is clear from the representation of 'Abraham' as the Lord as regards the Divine celestial or Divine Good, dealt with many times already; from the meaning of 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009; and from the meaning of 'a son' as the rational, dealt with in 2623, as well as from the meaning of 'born to him' as being manifested from the Divine. From this it is evident that 'Abraham called the name of his son born to him' means that the nature of the Rational was such that it was Divine. From these few words the following three arcana shine through to those who possess the internal sense. The first is that the Lord's Divine Human was a manifestation from the Divine itself, an arcanum which is explained further in this verse; the second is that the Lord's Divine Human was not only conceived but also born from Jehovah, and therefore the Lord as regards the Divine Human is called the Son of God and the Only Begotten, John 1:14, 18, 49; 3:16, 18, 35-36; 5:19-27; 6:69; 9:35; 10:36; 11:27; 14:13-14; 17:1; 20:31; and similarly in the other Evangelists; and the third arcanum is that the Lord's Divine Human is meant by the name of Jehovah, that is, His nature, see John 12:28.
