Revelation 3:4-9

4But you have a few individuals in Sardis who have not stained their clothes, and they will walk with me dressed in white, because they are worthy.

5The one who conquers will be dressed like them in white clothing, and I will never erase his name from the book of life, but will declare his name before my Father and before his angels.

6The one who has an ear had better hear what the Spirit says to the churches.’

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.
