There's so much to say!
You see, the idea of the union of Heaven and Earth is reflected on the symbolic meanings of Three, Seven and Marriage. I'm reminded of the Wedding Ring. Gamos (Marriage) = 314 => Pi => Circle => Wedding Ring.
Thus we read of (and visualize in the Canon Wheel) the union between Heaven and Earth in the Third Cycle, which corresponds to the Seventh Canonical Division, ending with the Marriage (Gamos) of the Lamb (depicted as Heavenly Jerusalem coming to Earth).
This image is prefigured in Genesis when Jacob dreams of a ladder that unites Heaven and Earth!
Gen 28:12 And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven: and behold the angels of God ascending and descending on it.But what does come next? Well, the next number that appears in the account is the Number Three:
Gen 29:1 Then Jacob went on his journey, and came into the land of the people of the east. This is the background that sets the scenario of the Marriage between Jacob and Laban's daughter! And the Number Seven appears next!
Gen 29:2 And he looked, and behold a well in the field, and, lo, there were three flocks of sheep lying by it; for out of that well they watered the flocks: and a great stone was upon the well's mouth.
Gen 29:20 And Jacob served seven years for Rachel; and they seemed unto him but a few days, for the love he had to her.
This sequence of images (Jacob's Ladder followed by a Marriage) is exactly what John repeats!
Joh 1:51 And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man. Therefore the structure of the Bible (Union of Heaven and Earth = Third Cycle = Seventh Division = Marriage) reproduces the pattern that is found in both Genesis and John! All the elements are there!
Joh 2:1 And the third day there was a marriage in Cana of Galilee.
But it seems like there's an element missing. Where is the Number Seven in John to complete the picture (heaven, earth, three, seven, marriage)?
Well, if we read John attentively we'll notice a day count there:
Joh 1:29 The next day [so this is the second day of the account] John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. So the marriage took place on the seventh day of John's account! The third day was also the seventh day! This strenghtens the link between the concepts of Heaven + Earth in the Third Cycle/Seventh Division.
Joh 1:35 Again the next day [so this is the third day] after John stood, and two of his disciples;
Joh 1:36 And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
Joh 1:43 The day following [the fourth day] Jesus would go forth into Galilee, and findeth Philip, and saith unto him, Follow me.
Joh 1:51 And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man.
Joh 2:1 And the third day [three + four = seven] there was a marriage in Cana of Galilee.
It is an infinite wonder. Of course there's much more!
