Revelation 2:7 (KJV)

Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.

But this thou hast, that thou hatest the deeds of the Nicolaitans, which I also hate.

He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.

And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive;

I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
