Some of us who are older have watched mainstream Christianity grow from a grassroots movement to an unwieldy giant. Wherever there is opportunity, people will step in and make use of it.
A minister can start out being called by God, walking in the power and favor of God, influencing people.... then as more people demand their time, they need to hire a staff to manage all the surrounding work.
The staff makes decisions, adds a board of directors for consultation, and then the minister's salary is increased. Buildings are constructed to house the increased numbers. Cameras and sound systems are purchased.... everything grows. What started out as the ministry of one believer becomes the occupational ministry of hundreds.
Then they need hotel rooms, private flights, conference room rentals, stadiums, more air time...
These ministries require expert technicians, MBA marketers... people skilled and committed to their areas of expertise.
When it gets to that point it's no longer what one speaker decides. It is a board of directors trying to manage a conglomerate of speaking tours, book publishing, tape distribution, emergency relief, schools.... the ministry grows into a city. (In fact, some seem larger than a city.) The speaker continues to teach, and lets everyone else do their job as the board sees fit.
The speaker acquiesces to suggestions about a better haircut, styled clothes, manicures, buffed shoes, spanks and eyebrow shaping. The speaker hires accountants to manage the book and tape royalties... and accountants insist the money needs to be invested in properties, to delay full taxes. Wealth grows, and appearances of wealth increase.
The clutter in a normal day increases to the point where the speaker has lost touch with how they started in the first place.
Growth is not necessarily good.
If you want to see the power of God work mightily among you, then recognize the responsibility of EACH member, to pray for each others' wellness, strength, and protection -- physical and spiritual. Feeding the monster of top-heavy leadership can sap the life out of a fellowship.
