In chapters 2 and 3 of Revelation, John writes letters to seven different churches. He affirms them for what they are doing right and corrects them for what they are doing wrong. It’s like a teacher giving feedback to help them become all they were designed to be.
For example, the church in Ephesus is commended for avoiding false teachings and enduring hardships, but they are told they have forgotten to love God and others. The church in Pergamum is praised for being courageous, but they are criticized for tolerating wrong behavior. And so on for the other churches.
The main point for us today is that Jesus wants us to be a people of love who avoid false teachings and endure hardships. We need to love God and others, and not be swayed by wrong beliefs. It can be tough, but Jesus promises us a reward if we stay faithful.
