This verse from 1st Timothy always hits me so heavily:
"[Elders] must manage their own household well...if a man does not know how to manage his own household, how will he take care of the church of God?" (1 Tim. 3.4-5)

The training ground for local church leadership is primarily the family and only secondarily a classroom, program or internship. You can't fake family. Family is not academic - it's real life, complex, complicated and relational. Impractical ideas and selfish motives are exposed in the day to day life of a family.

The Apostle Paul wanted church leaders to function like Fathers and Mothers, not CEO's, coaches or "influencers."

This actually reveals a great deal of how Paul understood God's design for the church - more like a family than an organization. In 1st Timothy alone Paul describes his relationship to Timothy; "my true child in the faith" (1 Tim. 1.2). Paul then instructs Timothy on how to relate to others in the church; "older men...as fathers...younger men as brothers, older women as mothers and younger women as sisters." (1 Tim. 5.1-2).

Paul related to Timothy as family. (1 Tim. 1.2)
Paul wanted Timothy to relate to others as family. (1 Tim. 5.1-2)
Paul wanted the church leaders to be good leaders of families. (1 Tim. 3.4-5)
Paul wanted people to first learn to practice their faith in regard to their own families. (1 Tim. 5.4)
Paul considered those who disregarded their families as “worse than an unbeliever.” (1 Tim. 5.8)

Imagine a church that develops people into spiritual fathers and mothers, instead of religious consumers.
Imagine a church that is built on relationships and not programs.
Imagine a church where the relationships are strong enough to withstand differences of opinion.
Imagine a church where the generations take turns caring for one another and showing honor to one another.
Imagine a church that's multi-generational.

This is the picture of what a Biblical, apostolic church looks like.
