With all that has been said, we must understand the mark and it's number
Revelation 13:18 "Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six."
Wisdom comes from knowledge, and all wisdom is from God, from wisdom comes understanding. We were told to "count the number of the beast". This was written in Greek, and the Greek word means more then counting numbers. You simple can't understand this meaning if you don't understand this Greek word. The word is #5585 in Strong's Greek dictionary, and it means to "calculate by counting the stones that are warn smooth over a long period of time."
What stones? We were told in chapter two, we would receive a new stone with a new name written on it. This word "count" originated from that word "stone" of chapter two of the book of Genesis. These are the only places in the Bible this word for count, or stone is used. So we must enumerate, or calculate these stones worn smooth over a long period of time. "Their rock is not our Rock, and his stones are not our Stones," is what the overcomers will sing, as the "Song of Moses tells us in Deuteronomy 32. God is our Rock, and Satan is the false rock, but which stones are we to count?
The stones are the number of man, that man is Satan, and if you know Satan you will know his children. Those stones are his children [offspring]. The "mark of the beast" number [6-6-6] then is to count, or know Satan's children over a long period of time. They are the "Kenites", the offspring of Cain, who was the child of Satan, through Eve, who was "beguiled in the Garden of Eden".
Jesus said in Revelation 2 and 3 that the Churches of Smyrna and Philadelphia were the only acceptable churches to Him, because they knew who the Kenites were. The Kenites were "those who said they were Jews, and lied; because they were of the synagogue of Satan". The seven churches are the seven types of churches existing in these last days. Five are not acceptable to God, while the two are.
One will either have the seal of God , or the mark
