I've painted a picture of the first six churches warned in Revelation 2:1-3:13, very definite periods and events as revealed in light of history. The final church period warned is Laodicea. I was especially impressed with this period because I see the evidences clear in our own time.
“Keep a constant watch. And pray that, if possible you may escape these horrors and stand before the Son of Man” (Luke 21:36)
“If you want me to protect you, learn to believe what I say” (Isaiah 7:9).
