3 Remember, then, what you were taught and what you heard; obey it and turn from your sins. If you do not wake up, I will come upon you like a thief, and you will not even know the time when I will come.
4 But a few of you there in Sardis have kept your clothes clean. You will walk with me, clothed in white, because you are worthy to do so.
5 Those who win the victory will be clothed like this in white, and I will not remove their names from the book of the living. In the presence of my Father and of his angels I will declare openly that they belong to me.
6 “If you have ears, then, listen to what the Spirit says to the churches!
7 “To the angel of the church in Philadelphia write:“This is the message from the one who is holy and true. He has the key that belonged to David, and when he opens a door, no one can close it, and when he closes it, no one can open it.
8 I know what you do; I know that you have a little power; you have followed my teaching and have been faithful to me. I have opened a door in front of you, which no one can close.
9 Listen! As for that group that belongs to Satan, those liars who claim that they are Jews but are not, I will make them come and bow down at your feet. They will all know that I love you.
