"And all these, though commended through their faith, did not receive what was promised, since God had provided something better for us, that apart from us they should not be made perfect." Hebrews 11:39-40
"1] So that we may obtain this faith, the Ministry of Teaching the Gospel and administering the Sacraments was instituted. 2] Through the Word and Sacraments, as through instruments, the Holy Spirit is given (John 20:22). He works faith, when and where it pleases God (John 3:8), in those who hear 3] the good news that God justifies those who believe that they are received into grace for Christ's sake. This happens not through our own merits, but for Christ's sake.
4] Our churches condemn [all churches and teachers] who think that through their own preparations and works the Holy Spirit comes to them without the external Word." [Augsburg Confession Article V: of The Ministry]
