The majority of WELS teens attend public high school and might have some connection to their home congregation through Youth Group and Young Adult programs (if they exist). Conversely, the majority of WELS leaders left home at age 14 for 12 years of seclusion boarding until age 26 at prep school, MLC/NWC, and MLS, therefore they never participated on a regular basis as active members of a normal WELS Youth Group or Young Adult program. They don't know what a good program looks like. Further, if they touch a good program, it dies.
Show me a good WELS Youth Group or Young Adult program that keeps young people active in the church, and I'll show you a program shepherded by a layperson.
