Is it necessary for the local church to continually try to enhance the spiritual formation of its congregation?

I think it is imperative for a local church to on regular occasion teach, disciple, lead, form, preach, model, etc. what it means to be a follower of Jesus. It is completely necessary, and if you are not doing this in your local church OR you think it can be done without a plan and therefore will happen naturally, you’re a fool.
