What is the possible connection between this promise and the threatening powers mentioned in 3:8?
Revelation 3:9 (ESV)
9Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but liebehold, I will make them come and bow down before your feet, and they will learn that I have loved you.
It would be logical to conclude that “those of the synagogue of Satan” generated the pressures the “little power” saints of Philadelphia successfully withstood. But the text does not explicitly say so.
9 Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie behold, I will make them come and bow down before your feet, and they will learn that I have loved you.
