Revelation 3:7-9

7“To the angel of the church in Philadelphia write the following: “This is the solemn pronouncement of the Holy One, the True One, who holds the key of David, who opens doors no one can shut, and shuts doors no one can open:

8‘I know your deeds. (Look! I have put in front of you an open door that no one can shut.) I know that you have little strength, but you have obeyed my word and have not denied my name.

9Listen! I am going to make those people from the synagogue of Satan – who say they are Jews yet are not, but are lying – Look, I will make them come and bow down at your feet and acknowledge that I have loved you.
