In Rev. 3:5 The angel of the Lord says to the angel of the church of 'Sardis': "...He that overcometh, the same shall be clothed in white raiment",...(in other words be enlightened and pure with the truth). The time period for the 'church' of 'Sardis' goes between @9,070 B.C. and @5,830 B.C.. He also says: "You have a name of being alive, and you are dead. Be watchful and strengthen the things which remain, that are ready to die; for I have not found thy works perfect before GOD."This is because there is no major pole star within this time period.
In Rev. 3:10 The angel of the Lord says to the angel of the church of 'Philadelphia': "Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come on all the world, to try them that dwell upon the earth." This church lasts from @5,830 B.C. until @2,590. Therefore this 'hour of temptation' must occur sometime after this time period of 'Philadelphia'. I believe this one hour refers to 1/12th of the circle or @2,160 years and is the time of the 10 kings/toes that are on the 8th head or church period. In Rev. 3:8 He then says: "I know thy works: behold, I have set before thee an open door , and no man can shut it: for thou hast a little strength, and hast kept my name." I believe this 'open door refers to the 'd' quadrant which is 'as a man's face'. 'd' stands for the word 'daleth', which means door in Hebrew. This 'd' quadrant begins at the end of 'Philadelphia' at @2,590 B.C.
It says in Rev. 3:11: "Behold, I come quickly, hold that fast which though hast, that no man take thy Crown." (ability to 'See-rown' the 'Great Clock'). Jesus came during the next period of 'Laodicea'. I believe Jesus will also be present during the 'Judgement Day', which shall occur sometime after this time period.
'G' is a symbol of this 'Great Clock' of the heavens and also the first letter of GOD. Also, 'Jesus' name sounds like 'G's-us.
Then the angel of the Lord says to the angel of the church of 'Laodicea' which houses the weak pole star 'Kochab': "I councel thee to buy of me gold ('G'-old) tried in the fire (of stars), that thou mayest be rich (in wisdom); and white raiment (enlightenment and purity), that thou mayest be clothed (in knowledge), and that the shame of thy nakedness (stupidity) do not appear; and annoint thine eyes with eyesalve ('I solve'), that thou mayest see (understand).
He then says to the angel of the church of 'Laodicea', which is 'Kochab' from Rev. 3:15-16: "I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth." This seventh church occurs between @2,590 B.C. and @650 A.D. I believe that sometime after this time period is when the people of the earth may be mostly annihilated because of war or a natural catastrophe like an asteroid or comet or super-volcano. Gradually the earth will be re-populated by those who have watched and prepared. This may be the people of the New Jerusalem talked about in Rev.21 that comes after this (as the new dispensation). During the 8th period of time 'Polaris', which is also part of this 'little dipper' and is situated at the mouth of the one who holds the keys.
The Spirit of the Lord says in Rev. 3:21: "To him that Overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in His throne."
