Resist and flee immorality or it will kill you

To the angel of the church in Thyatira write:

These are the words of the Son of God, whose eyes are like blazing fire and whose feet are like burnished bronze.

I know your deeds, your love and faith, your service and perseverance, and that you are now doing more than you did at first.

Nevertheless, I have this against you: You tolerate that woman Jezebel, who calls herself a prophetess. By her teaching she misleads my servants into sexual immorality and the eating of food sacrificed to idols.

I have given her time to repent of her immorality, but she is unwilling.

So I will cast her on a bed of suffering, and I will make those who commit adultery with her suffer intensely, unless they repent of her ways.

I will strike her children dead. Then all the churches will know that I am he who searches hearts and minds, and I will repay each of you according to your deeds.

Now I say to the rest of you in Thyatira, to you who do not hold to her teaching and have not learned Satan's so-called deep secrets (I will not impose any other burden on you):

Only hold on to what you have until I come.

To him who overcomes and does my will to the end, I will give authority over the nations--

He will rule them with an iron scepter;
he will dash them to pieces like pottery'
just as I have received authority from my Father. I will also give him the morning star. He who has an ear, let him hear what the Spirit says to the churches.
