Willow Creek Repents
All those concerned about how churches produce spiritually mature believers should find the following link fascinating: http://blog.christianitytoday.com/outofur/archives/2007/10/willow_creek_re.html
Bottom line: spiritually mature people grow as they are equipped for:
1. Scriptural study/application
2. Spiritual disciplines: how to practice the biblical/historical disciplines of the spiritual life
3. Spiritual friendships: how to engage one another in biblical relationships.
And it took 30 years, 100s of programs, and millions of dollars to figure this out?
