Revelation 2:1-7 (KJV)
1 Unto the angel of the church of Ephesus write; These things saith he that holdeth the seven stars in his right hand, who walketh in the midst of the seven golden candlesticks;
2 I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
3 And hast borne, and hast patience, and for my name's sake hast laboured, and hast not fainted.
4 Nevertheless I have somewhat against thee, because thou hast left thy first love.
5 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.
6 But this thou hast, that thou hatest the deeds of the Nicolaitans, which I also hate.
7 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.
