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.

3222. In addition to this, loves and the affections belonging to them are represented by means of flames, which are indescribably varied. Truths however are represented by means of lights and by means of countless modifications of light. From this it may be seen how it comes about that flames in the Word mean goods that are the goods of love, and lights truths that are the truths of faith.
