Their letter concluded by saying that they were worried that their churches were becoming like those at Laodicea and Ephesus, mentioned in Revelation, lukewarm and losing their first love. But theirs are not the only churches in this condition. My experience is that in the more doctrinal churches there appears more correctness than devotion and in churches where there is more excitement in Sunday worship this often seems more to do with that particular church culture than genuine love for Christ.
