righteousness obtained through faith means it is nothing that I have done but with faith in God and Christ's dying for me on the cross, it washes me white as snow. It means the Jesus cleanses me and I put on His righteousness.
righteousness by the law means I have to constantly try to do all the right things and to say all the right things to try and make myself acceptable to God. I cannot do that. It is impossible.
I don't think it is a major issue, but I am sure some of the congregation struggle with it.
I am not sure about Society's view, I think they believe we all should act and behave a certain way and if we don't they might question our Christianity.
because we feel we need to do something to obtain it, people question the things that are free, that are there for the taking.
