What is the church according to the one who holds the seven stars and walks among the seven golden lampstands?

What is the church according to the one who hold its spirit and message in his hand and walks among it?

“This is what the one who holds the seven stars in his right hand says, the one who walks in the midst of the seven gold lampstands: ‘I know your works, and your labor and patient endurance, and that you are not able to tolerate evil, and you put to the test those who call themselves apostles and are not, and you found them to be false. And you have patient endurance, and have endured many things because of my name, and have not become weary. But I have this against you: that you have left your first love. Remember therefore from where you have fallen, and repent and do the works you did at first. But if you do not, I am coming to you, and I will remove your lampstand from its place, unless you repent. But you do have this: that you hate the deeds of the Nicolaitans, things which I also hate. The one who has an ear, let him hear what the Spirit says to the churches. To the one who conquers, I will grant to him to eat from the tree of life which is in the paradise of God.’
