The price of being a Christian can be very high in a hostile environment. That apparently was the case in Smyrna. Through persecution they had been purified and had come to a serious kind of Christianity. Through persecution they had been deprived, but in their poverty, they had become spiritually rich

Revelation 2:1-11

“To the angel of the church in Ephesus write: ‘The words of him who holds the seven stars in his right hand, who walks among the seven golden lampstands.

“‘I know your works, your toil and your patient endurance, and how you cannot bear with those who are evil, but have tested those who call themselves apostles and are not, and found them to be false. I know you are enduring patiently and bearing up for my name’s sake, and you have not grown weary. But I have this against you, that you have abandoned the love you had at first. Remember therefore from where you have fallen; repent, and do the works you did at first. If not, I will come to you and remove your lampstand from its place, unless you repent. Yet this you have: you hate the works of the Nicolaitans, which I also hate. He who has an ear, let him hear what the Spirit says to the churches. To the one who conquers I will grant to eat of the tree of life, which is in the paradise of God.’

“And to the angel of the church in Smyrna write: ‘The words of the first and the last, who died and came to life.

“‘I know your tribulation and your poverty (but you are rich) and the slander of those who say that they are Jews and are not, but are a synagogue of Satan. Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation. Be faithful unto death, and I will give you the crown of life. He who has an ear, let him hear what the Spirit says to the churches. The one who conquers will not be hurt by the second death.’
