Thougths on Revelation 3: Ancient churches and modern problems

Sardis
It's a little harder for me to draw a comparison of the church in Sardis to modern churches because the message to them is somewhat vague.  I don't know if the "deeds" are good works or if they are personal actions.  So, my best parallel is to the modern mega-church.  These churches have a lot of influence and resources.  They are perceived as "alive".  My question is always, what are these churches doing with their resources? What percentage of the congregation is actually living the Christian life?  What is the church doing to improve their community and bring their community to Christ?  I know a lot of mega-church pastors struggle with these issues, but I wish all of them did.

Philadelphia
The church in Philadelphia reminds me (somewhat) of very small churches that struggle to remain faithful when surrounded by things that make it difficult.  It is a big challenge for small churches to remain faithful and not get discouraged.  The promises made to the Philadelphia church are what I find most interesting.  He promises to spare them from the coming turmoil and to make their oppressors acknowledge that God loves them.  I'm not sure what to make of these promises, but I do find them interesting.

Laodicea
First a little bit of a geography lesson to help better understand the message.  Laodicea probably was near a medicinal hot spring.  It was also near a cold river.  The river was refreshing for drinking.  The hot spring was good for health.  When the river ran into the hot spring, it turned lukewarm and good for neither refreshment nor health.

With that out of the way, Laodicea reminds me of too many modern suburban churches in the US.  They have great wealth, but they don't do anything with it.  They follow a script designed not to make anyone too uncomfortable in the services.  They host extra programs for different groups in the church to make the members feel more comfortable.  Overall, the churches are very comfortable.  But, what does that actually mean?  Are they refreshing for people in need of refreshment?  Do they heal spiritual wounds?  No.  That would make some people uncomfortable.  You can't make people uncomfortable.  Therefore, you should just remain in your church bubble and spend time with others who are comfortably like you and not do anything to rock the boat.  And God will vomit you out of His mouth.
