ok i dint say i dont read the bible, then these groups arnt age bracketed, anyone of any age is welcome, but the majority is younger adults, so everyone is welcome cause like you said they can give inspiration and help to young people too, i think they should be there just incase someone relates with them better then someone else, this is really a starting point to get people in church then them go home and there own questions and look them up, or check up on the speaker i do it all the time anytime a scripture flies out i look it up at home to see for myself that way when im talking to people like you i know what im talking about.
