Christ severely criticizes the church of Pergamos for the doctrine of Baalam and idolatry. Nevertheless, to those who overcome, He will grant eternal life.
Contrary to Protestant understanding, our works emphatically do count - showing or demonstrating (not just telling) that we will be obedient.
Cultural compromise, such as found in Pergamos, brings judgment from Jesus. To those who refuse to compromise their convictions, Christ promises eternal life.
Christ cautions the Pergamos congregation to shun the doctrine of the Nicolaitans. The Church suffers when it harbors those who compromise and offend.
