As we face the terrifying challenges of climate change today, the spiritual power we require will only come when we surrender every particle of our will and life into the hands of the living God - when we die to ourselves in order to participate in the transformational inbreaking of the Kingdom of God on earth. In this deep and challenging lecture, Eden Grace explores the biblical, historical and spiritual roots of Quakers' contemporary witness to God's creation. The chapters are interspersed with several profi les of faithfulness from Friends around the world, and a comprehensive study guide provides an opportunity to gather and refl ect on how God might be calling Friends to prophetic and transformative witness in our time. Eden Grace is a member of New England Yearly Meeting and serves as the Director of Global Ministries for Friends United Meeting (FUM). Prior to this, she spent nine years as FUM's Field Offi cer at the Africa Ministries Offi ce in Kisumu, Kenya, where she helped African and North American Quakers move away from donor-centric relationships to develop more reciprocal partnerships. Eden describes her ministry as "decolonising Quakerism".
