(18) The disciples said to Jesus, "Tell us how our end will be." Jesus said, "Have you discovered, then, the beginning, that you look for the end? For where the beginning is, there will the end be. Blessed is he who will take his place in the beginning; he will know the end and will not experience death."
There is no time. The Alpha et Omega. The beginning in the end, the end in the beginning. Malkuth in Kether. Etc., etc. This is an age-old principle, and one that we can safely assume has true value among all traditions that hold it. However, let's also look at this in terms of Gnostic mythology. The Gnostic does not see Genesis as the beginning, but that which happened before that - i.e. the True God in the Pleroma, with Sophia and the Aeons, etc. Thus, to know about the end, the return to the Pleroma, we must know about the beginning, the true beginning. Indeed, it is with this knowledge of this creation myth, which the Gnostics held in great esteem, that the quest for the "end" (Gnosis, etc.) begins.
