In all of the messages to the churches Jesus says, “I know your works” and He gives them a promise. In this message, the promise is: “To him that overcometh will I give to eat of the hidden mannah, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth it.”
Rev 2:12-17
There were some people from the church of Pergamos that had compromised by eating things sacrificed to idols and committing fornication. These are the two things that the Lord specifically warned us to flee from. Acts 15:28-29
Also, there were some that held the doctrine of Balaam. Which taught the children of Israel how to do wicked things.
This is a warning for us also! Matt 18:6
And there were some that held the doctrine of the Nicolaitanes, which thing Jesus hates. A doctrine is a belief, and what you believe determines how you behave. What is your doctrine? Do you believe that you came from a rock 4.6 billion years ago? Do you hold to the doctrine of Evolution?
Jesus told them to “repent, or else”. He gave them a warning. We are living in the last days according to the Bible. Heb 1:1-2
And that means that if you need to repent, you should soon!
Rom 10:9
