Nicolaitanes means exactly, the 'Conqueror of the laity' Those distinct from the clergy. In short, the Church, the Earthly Church.

Revelation 6:2 And I saw, and behold a white horse: and he that sat on him had a bow; and a crown was given unto him: and he went forth conquering, and to conquer.

And so they did, going around the world, conquering the people with the Law and Prophets (The Bow) and the New Testament (The Crown), by manipulation, lies, force, wars and slavery. All the while, making merry in his name, giving gifts every Christmas and Easter. 

Revelation 11:10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets (Jesus and the Father, who inspired the scriptures, which bare witness of Jesus) tormented them that dwelt on the earth.

With the truth of righteousness, since the unrighteous are tormented by righteousness, like magnets that repel each other. As Jesus said, he will fight against them with the sword of his mouth, and that sword is the word of God. 

Psalm 55:21 The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.

The religious and spiritual themselves claim themselves to be righteous, riding on the white horse, a horse stolen from Jesus, who is the servant of righteousness, in his Father's house the spirit, which they have turned into a 'Den of Thieves' A building made with hands, which people worship in instead of in the spirit. In that court without the spiritual temple.

A Holy City, the City of peace, Jerusalem,which is a parable for the spirit, that they tread underfoot with Earthly beliefs, the teachings of Balaam, which seduce the people, and the doctrines of the Nicolaitanes which conquers the people. They have their own traditions and rituals, that serve only the flesh, and not the spirit. As Jesus said, he didn't like them amongst those called out by God in the (Church) built without hands, since they corrupted the teachings of Jesus. They talk of God, but don't turn him. They talk of Jesus, but don't do as he says. Hearers of the word but no doers.

2 Corinthians 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?

The spiritual church, the Rock on which revelation is built, was as the Church Jesus set up in the Father name. Peter was the first of Jesus disciples to receive revelation (And yet he still denied him three times, do not underestimate the power of the soul, the wicked ones child within you, or others, keep watch always).

Matthew 16:17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.

And remember not to fight against flesh and blood as the religious do, causing wars, terror and general oppression, the real enemy is also within, that works within all people, that 'Son of Perdition'

Ephesians 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.

The word Church means Ekklesia, which means to call out of the world.

1 John 5:3-4 For this is the love of God, that we keep his commandments: and his commandments are not grievous. For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.

The Called out ones, who were Jesus Apostles, which is who Saul of Tarsus persecuted himself, until converted directly by Jesus himself, in spirit, which made Saul a called out one himself. A true follower of Jesus Teachings, doer of the word. After all all his followers wrote something after his death, preaching the Gospel. Whereas today, they stand in church, dancing like circus animals, clapping hands, singing songs, with their hallelujah's and praising Jesus, all the while orchestrated by their animal trainer.

1 Timothy 4:1-4 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron; Forbidding to marry (Wonder which religions do that), and commanding to abstain from meats (Or does this), which God hath created to be received with thanksgiving of them which believe and know the truth. (Then again, this is the spiritual meat, but you're free to eat what you want, but give thanks to the Father for his Grace, his revelation, the knowledge of truth that he reveals to you) For every creature of God is good, and nothing to be refused, if it be received with thanksgiving:

Whereas every creature of the Earth, seeks to seduce and conquering the minds of the people, deceiving the hearts of the simple..

Romans 16:18 For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.

Yes, the ignorant captivated by long beautiful sermons in their Churches, Temples etc, think they're saved just by the hearing of the word. But they do nothing, they listen to man, and not God, they turn to man but not God. I speak of those who perform miracles (Sermons) in front of the beast that causes the beast image to speak. (The Church hierarchy, and the members they rule over, the lay people)

Revelation 13:15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, (Via the Church Hierarchy) and cause that as many as would not worship the image of the beast should be killed. (I'm sure the history of religion should be fresh in people's minds)

 You'll probably learn more watching animals in a circus, as much as being a member of one. The outcome is pretty much the same.

Revelation 2:6 But this thou hast, that thou hatest the deeds of the Nicolaitanes, which I also hate.

All these were prophesied in the Old Testament, and by Jesus himself, continuously warning people not to follow man, nor be deceived by man by any means.

Deuteronomy 28:48 Therefore shalt thou serve thine enemies which the Lord shall send against thee, in hunger, and in thirst, and in nakedness, and in want of all things: and he shall put a yoke of iron upon thy neck, until he have destroyed thee.

How's that crucifix around people neck, that yoke of iron, with the image of Jesus naked, in hunger, in thirst and in want of all things. On Satan's Cross of execution, that strangely people love to put around their necks.

Revelation 13:14 And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.

That image of a dead man on a cross, which was wounded by the sword, (Pierced by a spear) but was raised up to Heaven and did live.

Psalm 69:21 They gave me also gall for my meat; and in my thirst they gave me vinegar to drink.

and;

John 19:28 After this, Jesus knowing that all things were now accomplished, that the scripture might be fulfilled, saith, I thirst.

Jesus serving his enemies, who are Christians, and who sent them against Jesus?, against his message from his Father. The LORD.

Matthew 15:8-10 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. But in vain they do worship me, teaching for doctrines the commandments of men.

And as he said about those that come in his name and deceive many.

Matthew 24:4-6 And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying, I am Christ (Christian); and shall deceive many.

Just who do you think he was talking about?

John 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.

What part of be taught of no man don't people understand, what part of you need no man teach you, don't people get? What was said about those who follow the doctrines of Baalam that SEDUCE people?

1 John 2:26-28 These things have I written unto you concerning them that seduce you. But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming.

What part of Jesus sending the spirit of truth which the world can't receive don't people quite grasp? SPIRIT of truth, not man of truth.

Matthew 7:21-23 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? (Like Christians claim to do) and in thy name have cast out devils? (Like Christians claim to do) and in thy name done many wonderful works? (Like Christians claim to do) And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

The religious can't shut up regardless of the truth rubbed in their faces. There's no quietness within the land of those people, thus they're incapable of  'Being still, and knowing God' in mind, nor mouth.

James 1:26 If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain.

Why? because they breed and spread unrighteousness. Do you only think that a religion that has paedophiles amongst them is going to help anyone, or at its core will teach the truth? Remember who the master of the house is.

Matthew 10:25 It is enough for the disciple that he be as his master, and the servant as his lord. If they have called the master of the house Beelzebub, how much more shall they call them of his household?

Righteousness cannot be yoked together with unrighteousness. And thus no religion or spiritual practice is of the truth, nor will any save people. They serve them, they also are of the members of that house, all the good and bad within that house. 

James 1:17 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.

The Father is ALL GOOD and produces only good, he shews mercy to all, the good and the bad, but  only produces good. Religion produces evil, so is not of God. It is that simple.

Matthew 9:17 Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.

The same way you cannot put new wine into old bottles, lest the old bottles tare and the new wine ends up on the floor.

2 Thessalonians 2:10-12 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: (What the religious deserve for deceiving people with religion, reaping what they sow) That they all might be damned who believed not the truth, but had pleasure in unrighteousness.

And anything not of the Father is unrighteousness. Jesus himself said call no man your Father on the Earth, but what do Christians do. Call man a Father in their Earthly churches. Looking up to man to save people, from what they know not what.

Yet they call claim to believe in Jesus and what he taught. Hypocrites as he called them. They pray and preach in public, claim to help the poor in public to be seen of men, just about everything Jesus said not to do they do, in his name, deceiving many. Seeking to convert others to their religions,and make no mistake, Christianity and Islam were born of Judaism, so think not that these things don't refer to them. Those three unclean frogs.

Matthew 6:2 Therefore when thou doest thine alms, do not sound a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, They have their reward.

And the Jewish didn't compass sea and land to convert people. Christianity and Islam however did. 

Matthew 23:15 Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves.

As he said, beware the leaven of the Pharisees and Sadducees, because their leaven lead to Islam and Christianity.

The same doctrines that lead to the religions of today, that have conquered the minds of the lay people. Scripture is the divinely inspired word of he Father, now abused to indoctrinate people into various religions and cults.

Hence the tag, a 'Den of Thieves' using something that doesn't belong to any religion, and a man of God doesn't remain a member of a religion or anything that has produced bad works, like wars, the abuse of children or investment of instruments of destruction, because they'll be of the same house of unrighteousness.
