William P. McDonald launches a comparative study of the theology and everyday ministry of Martin Luther and John Wesley.

McDonald recounts the spiritual lives and writings of two of Christianity's foundational theologians, revealing a disparate, yet nonetheless generative, conversation about what it means to live a Christian life. McDonald provides a series of theological snapshots which maintains the nuances inherent to Luther and Wesley's alternative, Christian theologies. This approach illuminates a productive dialogue on issues which plague many contemporary believers, including spiritual despair, sinfulness, and access to God. Fundamentally, this book functions as a work of ecumenism and invites believers across Christian denominations to find community through the shared challenge of seeking and wrestling with faith.
