Jesus gave a message to Philadelphian Christians in Revelation 3:7-13. What does the "open door" have to do with? Does Philadelphia mean 'brotherly love'? How can that love be demonstrated? When did the Philadelphia era of the true Church of God begin? What did Herbert W. Armstrong teach about the purpose of the Philadelphian era? What about proclaiming the gospel of the kingdom of God? Are Christians supposed to be pilgrims, sojourners, and ambassadors for the Kingdom of God? What about being a pillar? Could God be calling you? What do we learn from the parable of the good Samaritan? What about the fullness/full number of Gentile (Romans 11:25)? What about supporting the poor? What about supporting proper church governance? What about fulfilling Matthew 24:14 and Matthew 28:19-20? How do Laodiceans differ? Why is there a Philadelphian remnant?
