The Fourth Gospel tells us that the Marriage at Cana, changing water into wine, was the first miracle of Jesus; which raises the question of - why then?
By my understanding; Jesus's miracles should primarily be understood as evidence of his primary creative power; that Jesus was divine and shared in God's creative power.
I also understood Jesus's baptism by John to be the moment when the Holy Spirit descended onto him and stayed; so that Jesus 'knew who he was' and also became divine (i.e. fully and permanently aligned with God's will)...
But if that was the whole story, then the question arises: why the 'gap' between the baptism and the first miracle?
The answer - I now believe - is that it was Jesus's marriage to Mary (Magdalene) at Cana which made possible the miracles.
The background to this can be found in my theological writings over the past years - and in particular my mini-online-book about the Fourth Gospel.
There can be found the arguments as to why this is the primary source on Jesus's life and teachings (qualitatively superior to any other source - whether Old testament, Gospel, Epistle, Revelation or otherwise).
Once this is acknowledged, it may readily be seen that we are clearly being told by the Fourth Gospel that Jesus married Mary at Cana; that 'this Mary' was the same as Lazarus's sister (Mary of Bethany) and Mary Magdalene; and that the resurrected Lazarus was author of the Fourth Gospel - Chapters 1-20 of which were written shortly after the ascension of Jesus (and, presumably, Mary his wife).
The other necessary understanding is of the nature of God and creation. I understand 'God' to be the dyad of Heavenly Parents - of the prime, divine man and woman; and creation to be the manifestation of their Love.
Taken together, this implies (although it does not entail) that the divine creativity of Jesus, as shown by his miracles, also required to be completed by a dyadic love between a man and a woman; which was made possible by the eternal/ celestial/ divine marriage of Jesus with Mary.
Until that point - Jesus could not perform miracles of divine creation; and this is why Lazarus took care to inform us in his Gospel that Cana was Jesus's first miracle.
