Who is in the Covenant?

I believe that everyone who was circumcised or now baptized and their family, children and unbelieving spouses included, belongs to the covenant family.

Although I'm not sure about the unbelieving spouse if they haven't been baptized. But I'm thinking that they are still included in the covenant, because Paul tells the believing spouse to not leave their unbelieving mate. We also understand that the two have become one and so I would think that the whole family would be included in the covenant.

I do believe that there are unbelievers and believers, or the visible and invisible church that all belong to the new covenant.

Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. - Galatians 2:16
