Revelation 2:5

2:5 Therefore, remember from what high state you have fallen and repent! Do the deeds you did at the first; if not, I will come to you and remove your lampstand from its place – that is, if you do not repent.

Revelation 2:21-22

2:21 I have given her time to repent, but she is not willing to repent of her sexual immorality. 2:22 Look! I am throwing her onto a bed of violent illness, and those who commit adultery with her into terrible suffering, unless they repent of her deeds.
