Revelation 2:12

AND THE ANGEL OF THE CHURCH IN PERGAMOS WRITE;

Pergamos means heights, as in they think they are high up in the kingdom.

THESE THINGS SAITH HE WHICH HATH THE SHARP SWORD WITH TWO EDGES;

This means it cuts both the flesh and the soul. When you hear the words of his mouth.

I KNOW THY WORKS AND WHERE THOU DWELLEST, EVEN WHERE SATAN'S SEAT IS:

Jesus is saying I know what you are doing. I know you have taken up an abode where Satan's throne is. Read Revelation 13:2; 16:10 these places will tell us about Satan's throne. Also read about it in Dan7:4-7.

AND HOLDEST FAST MY NAME, AND HAS NOT DENIED MY FAITH,

I know you call yourselves christians and that you have kept the faith of me.

EVEN IN THOSE DAYS WHEREIN ANTIPAS WAS MY FAITHFUL MARTYR, WHO WASSLAIN AMONG YOU, WHERE

SATAN DWELLETH.

This is talking about the future, when Satan will be here on earth, because he was kicked out of heaven. Revelation 12:7-9 "And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,"

Did you know there would be a fight in heaven?

Did you know Satan had his own army of angels?

"And prevailed not( Satan did not win the light); neither was their place found anymore in heaven."

Did you know Satan and his angels are still in heaven dght now?.

"And the great Dragon was cast out" ( One of the roles satan plays is the dragon, which is the same dragon when he is kicked out of heaven will come down to earth and take control of the one wodd system. Revelation 13:11-14. What is his purpose, to deceive those that live on earth.)

"that old serpent" (another role Satan has played in this earth age, Did you know satan was the serpent that deceived Eve in the garden? Genesis 3:1-5 His purpose again was to deceive.)

"called the devil" (another name people call him)

"and Satan" ( The name Satan means the accuser. This is what satan is doing dght now in heaven. Revelation 12:10-11 "And I heard a loud voice saying in heaven, now is come salavation, and strength, and the kingdom of our God, and the power of Christ: for the accuser of our brethren is cast down, which accused them before God day and night. And they overcame him by the blood of the lamb, and by the word of their testimony; and they loved not their lives unto death.")

The reason The Father used all these names of Satan in one place, is so that we would know it is all the same entity. We would have no room for doubt.
