Luther: Christian, You Are Isaac

Therefore just as Isaac has the inheritance from his father solely on the basis of the promise and of his birth, without the Law or works, so we are born as heirs by Sarah, the free woman, that is, by the church. She teaches, cherishes, and carries us in her womb, her bosom, and her arms; she shapes and perfects us to the form of Christ, until we grow into perfect manhood (Eph. 4:13). Thus everything happens through the ministry of the Word. It is the duty of a free woman to go on giving birth to children endlessly, that is, to sons who know that they are justified by faith, not by the Law.
