The Seven Golden Candlesticks
Revelation 2:1bThese things saith He that holds the seven stars in his right hand, Who walketh in the midst of the seven golden candlesticks;
This is Yahushua, walking among the assemblies observing our actions in His name.
Revelation 2:6 But this thou hast, that thou hatest the deeds of the Nicolaitans, which I also hate.
Revelation 2:15 So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate. Yahushua, God hates Nicolaitians what and who are they? They were people in the church who said you could eat things sacrificed to idols and used their ministry for gain, either wealth or power. Hierarchy creation, pastors and teachers are above and not servants to all. Yahushua was a servant to others not lording over them. His servants/anointed apostles;  prophets; evangelists; and some, pastors and teachers; are to perform in service, to the perfection of the saints. Ephesians 4:11-13 He is the light of the world and you are the light of the world.
Revelation 2:9 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.  This term is used twice and is referring to people who hold to the letter of the book and not the spirit of the precept of love. They are loveless in their approach and judgment of others. These warnings are not just for groups but to individuals for self inspection. We can easily fall into these traps. Yahushua is telling us for our warning and knowledge of what to look out for. Should we discount these warnings? Are there consequence, for our actions, our works? Yahushua says: Revelation 2:23 I will give unto every one of you according to your works.

Father I know I have come short and unrighteousness has been found in me but knowing the truth of Your Sons sacrifice, I humble myself before you for that cleansing blood of the covenant. Confessing my faults to you and my friends, receiving the cleansing of Your Spirit and turning that this iniquity is broken forever and by my submission to Your Word, I am able to resist satan and he will flee. Your love and mercy endures for ever and ever, the power of Your Sons love and guidance of His Holy Spirit in our lives working for that great reward for those who reverence your name.
Halle lu YAH
Amen
