They absolutely are the same individual but what you are seeing is the much more mature and understanding individual.
The one exception is in the Revelation. This is where the bible got screwed up because the council of Nicea lost track of who was where. In the first chapter of the Revelation of John of Patmos, they mistakenly placed the Old Man in the wrong role. They placed the creature of light in the creature of darks role.
The mystery of Revelation is a mystery because the council had no idea what the seven stars and "lampstands" were so they made something up. In reality, if the creature of dark was in the right role, the seven stars and seven lampstands are talismans and sigils, which are the tools of a sorcerer.
The council of elders-: where the hell is the Old Man going to find one elder, let alone twenty four of them.
The rape of Jezebel - pull-ease!
Extorting others to purchase gold from Him! Really?
In Revelation 12 they give Him an illegitimate child.
By the reversing of the CoL and the CoD, it actually reverses the entire bible. The entirety of the main tenet of christiandom is reversed.
Also, in Revelation 13, He is the personification of the red dragon, as the bible was framed from ancient texts that were of Babylonian and Sumerian origin, and the supreme being in both cultures was represented as a dragon. Marduk was the Babylonian representatation and I do not rightly recall the Sumerian god, but the council had already lost understanding at this point.
The deal is that the seven headed beast is the son of God, and the red dragon "gives the beast his power and his seat" is metaphor for "divine right", which is the Old Man.
The creature of dark is not the Antichrist nor is it Satan. When you understand that the bible has no message of good hope, it is entirely an eschatological prophetic foretelling that had already come to pass thrice on this planet and there are indications and evidences that it has challenged before on at least one other.
The council did not understand this or did not care about the notion of truth, it didn't fit into their falsehoods. The creature of dark changes every time it comes to pass. Just like the Melchizedekk changes.
The individual that was the creature of dark in the last time it all came to pass was in the last battle of good and evil that must be fought to end the Age, just before the flood of Noah, and is recalled in the Mahabharata. The individual that sat in the creature of dark role, was rudra dwho was an albino, hence the white hair and eyes of fire.
So, with the above exceptions the God of the old testament is the god of the new testament, who had commandEd demeritus status shortly before the flood of Noah.
The reason I know this is that I am the first individual since Moses to function as Clarion for the On High. That's 75,000 years.
