Thyatira was a church that was steeped in sin. They had a female prophetess who unabashedly led the people into idolatry and sexual sin. While there were those in the church that rejected her false doctrines and lifestyle, the Elders of the church turned a blind eye to the sin. This warning from Jesus Christ goes to every church in every generation to rid sin from the church. A failure to do so will result in exacting judgment. The overcomers, however, will be rewarded beyond measure.
Pergamos was a city centered in pagan religion. The church there began to compromise with pagan beliefs which led to a stern rebuke by Jesus Christ. Today this message from Christ serves as a warning to our churches not to compromise with false teaching and sinful living. Those churches and believers who stay loyal to Christ will be rewarded greatly.
Smyrna was a church under heavy persecution in the first century. Christ commended them for enduring through the thick and thin. Today our churches are not facing this kind of tribulation yet, but many churches around the world are. This message will encourage believers to pray and support those persecuted churches since they as part of the body of Christ.
