Revelation 2 begins the specific letters to individual churches. In every letter the phrase "I know" will appear and will direct the church to refocus her attention on obedience to the Spirit. Almost in every case there is commendation and rebuke, encouragement and admonition.
If the Spirit were to write you a letter today, what would it's content look like? What would God be commending? What would He be challenging you to do? Don't you think it would be a good idea to listen to Him and do what He says?
Let's decide to obey today.
