According to scripture, in what sense are believers meant to be ‘accountable’ to a local church group?

I have often heard it said that believers need to be members of a local church in order to be ‘accountable’. I am assuming all believers understand that they should regularly fellowship with a local church. My question is not about that. My question is from the scripture in what sense might this accountability mean? I am not sure the word accountable is actually used in the New Testament except that the whole world is accountable to God by the Law but I take it to mean in certain situations some form of answerable agreement of conduct, or something along that line is implied by various bible verses which make people chose the word ‘accountable’ as though people were accountants making some kind of record or enforcement of some basic standard. What does it actually mean? What are its limits? What sense does the scripture support or limit such a concept?
