Revelation 3:5

2 Wake up and strengthen the things that remain, which you were about to throw away, for I have found no works of yours perfected before my God.

3 Remember therefore how you have received and heard. Keep it and repent. If therefore you won’t watch, I will come as a thief, and you won’t know what hour I will come upon you.

4 Nevertheless you have a few names in Sardis that didn’t defile their garments. They will walk with me in white, for they are worthy.

5 He who overcomes will be arrayed in white garments, and I will in no way blot his name out of the book of life, and I will confess his name before my Father, and before his angels.

6 He who has an ear, let him hear what the Spirit says to the assemblies.

7 “To the angel of the assembly in Philadelphia write: “He who is holy, he who is true, he who has the key of David, he who opens and no one can shut, and who shuts and no one opens, says these things:

8 “I know your works (behold, I have set before you an open door, which no one can shut), that you have a little power, and kept my word, and didn’t deny my name.
