Rev 2:8 And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive;  I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan. Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life. He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death.
Problems at Smyrna (2:9-10)
The church at Smyrna apparently suffered at the hands of a group “who say they are Jews and are not but are a synagogue of Satan” (2:9). These Jews thought they were the people of God but were actually the representatives of his adversary (John 8:31-47).
The way a church can be like Smyrna is have a group who say they are Christians and or not!
Why are these people said not to be Jews? They were Jews by race and religion. But they were not spiritual Jews, in the sense that the New Testament defines a Jew. Paul made the point in his writings: “A man is a Jew if he is one inwardly; and circumcision is circumcision of the heart, by the Spirit” (Romans 2:29). The church saw itself as the Israel of God, the “true circumcision” who worshiped God in Spirit and put its faith in Jesus Christ (Philippians 3:3)
Therefore, the first thing we should text is our heart circumcised by the Holy Spirit?
