Philadelphia Church
Revelation 3. 7 to 13:
7- And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;
Jesus places himself as the Saint, the truthful, that´s what his followers also have to be, because we are in a time of many fakes, who adore a fake god, and a fake Christ.
8- 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 word, and hast not denied my name.
E He shows us that those that are faithful in the Word, even if they have little strength, will open any door that the powerful, fake Christians will try to close.
They´ll be humiliated and defeated by those

faithful to the Word, like darkness can´t resist to light.
9- Behold, I will make them of the synagogue of Satan, which say they are Jews (Christians), and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
The Philadelphia and the Church of Smyrna (the one of the persecution), in both, says that we are in the synagogue of Satan, and doesn´t say to leave, but to open the door and, with Jesus, purify the Laodicea, making her perfect Philadelphia.
10- Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
In the period of the 4th Seal, of hunger, virus and violence, where one quarter of the people will die to test who is a Christian.
