Are all they saved who hear the gospel, and live in the church?

All that hear the gospel, and live in the visible church, are not saved; but they only who are true members of the church invisible.

Proofs

All that hear the gospel, and live in the visible church, are not saved; but they only who are true members of the church invisible. (John 12:38–40; Romans 9:6; Matthew 22:14; 7:21; Romans 11:7)
