The deeds of the Nicolaitans are the culmination of three doctrines that Jesus hates: the doctrine of Jezebel; the doctrine of Balaam, and the doctrine of the Nicolaitans.
The deeds characterise the activities of the “great harlot” who has corrupted the world with false religion.
Nicolaitans are very active in the world today, assiduously working toward a unified system of self-worship; one world church that has nothing to do with the God of the Bible.
Most of the weird practices we have in the church system today emanated from the deeds of the Nicolaitans that Jesus hates.
If you are a follower of Christ, you must hate what He hates.
