In this Lecture, Margery Post Abbott explores the interplay between faith and action, drawing on her wide range of experiences as a scholar, activist, sailor and Quaker. Taking an ethical stance, acting on the concern for justice and the yearning for peace, does much to open hearts. Yet some activists get burnt out or caught up in the tangle of power or pride, becoming what they were resisting. Friends have always asserted that there is a source of strength and guidance that, paraphrasing William Penn, changes the human heart so that each person might better change the world. This Spirit fuels the work for which Friends are most known. Faithfulness to the Inward Guide lifts us free of the desire for personal success, or for revenge, or for control over the world around us. By listening for and following the Voice of the Light, each of us might become an Everyday Prophet. Such people walk humbly even as they come to speak boldly, following the path of compassion and justice. We do this best as part of a community that is able to carry a vision of the New Creation, the Kingdom of God, being formed on earth as we remind each other to listen for the movement of the Spirit and be open to a fresh way of being.
