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.

6947. 'What is that in your hand? And he said, A rod' means the power of the Lord's Divine Human. This is clear from the meaning of 'hand' as power, dealt with in 878, 3387, 4931-4937, 5327, 5328, 5544; and from the meaning of 'a rod' too as power, dealt with in 4013, 4876, 4936. The reason why it is the power of the Lord's Divine Human is that 'Moses' represents the Lord in respect of the law of God, which is the Word, and this is Divine Truth emanating from the Lord's Divine Human, 6752. The power meant by 'hand' is the power emanating from the Lord's Divine Rational, whereas the power meant by 'the rod' is the power emanating from the Lord's Divine Natural. The reason why 'a rod' is the power emanating from the Lord's Divine Natural is that a rod is like a foot in that it supports the body, and by 'the foot' is meant the natural, 2161, 3147, 3761, 3986, 4280, 4938-4952; and 'lifting up the hand' is power in the spiritual, while 'lifting up the foot' is power in the natural, see 5727, 5328. And since 'hand' and 'rod' have these meanings, then depending on how high the things described in the internal sense rise Moses was sometimes told, when he was to work miracles, to lift up his hand, at other times his rod.
