Mike Bickle addresses the church of Pergamos in Revelation 2:12-17, emphasizing the dangers of compromise within the church. He highlights three groups: those who are faithful, those who compromise, and those who tolerate the compromise without taking a stand. The Lord calls for repentance from all groups, warning that He will act decisively against those who embrace false teachings that promote sin under the guise of grace. Bickle encourages believers to remain steadfast in their faith and to confront false doctrines that lead to spiritual compromise, reminding them of the promises given to those who overcome.
