Jesus talked about the need for new wineskins. New wineskins allow room for the body of Christ to manifest supernatural heart-connection between Christ-followers. Old wineskins have hardened into religious systems and traditions.
Systems are great and help humans function in orderly ways, however, Christ calls us beyond religious systems into new wineskins that create close relationship with Him. The old wineskin of sermons tell people what to do, without giving them any hands-on training in doing it.
New wineskins are rare and hard to find. I wrote a book about them. Search Amazon for: Beyond Church.
