I was a member of a Charismatic fellowship (Baptist) for 3 years and a member of a Pentecostal fellowship for 5 years. I was a youth leader at the latter. The Baptists had a regular gospel meeting devoted to unbelievers, which I believe is the correct approach. The Pentecostals had an open door policy. One of the problems I saw was that relatively few of the people attending were in fact born again. Paul Washer maybe a bit extreme, but he's not far wrong about the shallow preaching that typifies much of the church these days.
The conservative types tend to be introverted and insular. Those groups are fading away. The Pentecostal/Charismatic types are m ore outgoing, but many employ unbiblical methods to attract people. No gets saved by absorbing a hyped up atmosphere. A number of Pentecostal churches here go by the title "Enjoy Church". Lord help us. The word of God is meant to convict, correct, rebuke and train in righteousness. We should be full of love and joy, but Christians should also know the discipline of God's word and leaders should be prepared to tell it like it is.
Shallow preaching produces shallow believers, if they are for real in the first place. The goal of the church should be the same as God's, which is to see people saved, but also to be brought to the knowledge of the truth. (1 Timothy 2:4) Once a believer knows the truth, nothing can move him. Half an hour on a Sunday is not going to do the job. I see preachers on TV who are more like motivational speakers, telling people how wonderful they are and how blessed they are going to be. You will fill your church with preaching like that. But they remain spiritual infants, unable to stand in the day of trial and not equipped to do battle in the spiritual war that we are all fighting.
Lord Jesus said that few enter the narrow path that leads to life. Be one of the few, whatever the cost. I can assure you that it is most difficult and demanding but also greatly rewarding.
