Hello gallenwalsh, I found these from Ray's papers, they are a very good read and I humbly suggest you read them.
Excerpt From 'Who is the Beast? - 666?'
@http://bible-truths.com/lake13.html
The Seven [COMPLETE] Churches of God represent the WHOLE CHURCH OF GOD in all generations. And so, what is it that God says those who are ALREADY IN THE CHURCH have to do if they are to overcome and be in the Kingdom of God? Answer:
"Remember therefore from whence you are FALLEN, and REPENT…" (Rev. 2:5).
THERE MUST COME A ‘FALLING AWAY’ FIRST
I have shown you that John, Paul, Peter, ALL of the apostles, the whole church in Asia, the Seven Churches of Revelation, the entire flock of God’s called, all built their houses upon spiritual sand—in other words EVERYONE ever called by God, falls, falls down, falls away.
The Proverb tells us that, "For a just man falls seven times…" That’s a COMPLETE fall. But strange as it may seem, this is necessary in God’s plan. What happens to a just man after he falls seven times? "…and RISES UP AGAIN" (Prov. 24:16). When he completely falls, he falls from grace. But for those whom God is both calling AND choosing, they will RISE UP AGAIN, for
"Who are you that judges another man’s servant? To his own master he stands or falls. Yes, he shall be holden up [made to stand up]: for God is able to MAKE HIM STAND" (Rom. 14:4).
We will ALL FALL! But afterwards, God "raises us UP AGAIN," and "makes us STAND." And from that time onward we have this sure promise of which we read before, but I want to read again:
"Now unto Him that is able to KEEP YOU FROM FALLING, and to present you FAULTLESS before the presence of His glory with EXCEEDING JOY, To the Only Wise God Our Saviour, be glory and majesty, and dominion and power, both now and ever. Amen" (Jude 124-25)!
When John’s spiritual house built upon the sand fell down, he was left, standing on the sand of the sea by himself alone with God, and it is then and only then, that he is able to see the wild beast that came up out of the sea.
This wild beast is further identified in Rev. 13:14 when we are told this
"…beast, which had the wound [deadly wound, Ver. 3] by the sword, and DID LIVE."
He was wounded to death, but the wound was healed and he again lived. He also has a mark, and a name, and a number. What is this mysterious number that has baffled scholars, theologians, and saints for centuries? I will not give you the complete answer to this at this time, but will only show you that it is the number of mankind—humanity.

Seven symbolizes completeness, six symbolizing just missing the mark (sinful humanity) of that completeness. Someday though we will all be complete in Him and Him in us.
Might I suggest you read Ray's 'The Book of Revelation is a Book of Symbols'

That would be a good start IMO.
As for the "connection" there is none, like Dennis said. Its just a number that symbolizes something else and can be used in many ways in Scriptures, and they dont necessarily have to be connected.
Hope this helps
