When John was in exile on the island of Patmos, the glorified Jesus appeared to him and gave him messages for each of the 7 churches in Asia Minor. Although these were 7 literal churches in Asia Minor, they are also typical of 7 periods of Church history.
The last church mentioned was in Laodicea. It presented a state of lukewarmness, indifference, materialism and apostasy which characterizes much of the Western Church today.
Of the 7 churches listed, this is the only church which receives no praise from Jesus. In fact Jesus is pictured as being outside his own church! - “I stand at the door and knock” (Rev 3:20). He is outside the door because he is not needed. They say, “I am rich; I have acquired wealth and do not need a thing.” (Rev 3:17)
Like Laodicea, in many of the Western churches today we have a lot of programs but no Christ! Paul says that in the last days people will “have a form of godliness but denying its power.” (2 Tim 3:1-5) i.e. occupied with religious ritual which has lost the significance.
