Grounds and Reasons of Christian Regeneration

William Law wrote this treatise in 1739 as a theological companion to his influential "A Serious Call to a Devout and Holy Life," addressing critics who questioned whether his demanding vision of Christian perfection was actually attainable. Where the earlier work had focused on practical devotion, "The Grounds and Reasons" provides the doctrinal foundation, exploring how fallen human nature can be genuinely transformed through divine grace. Law was responding to both antinomian tendencies that dismissed moral effort and rationalist theology that reduced Christianity to ethical improvement, seeking instead to articulate a robust theology of regeneration that honored both divine sovereignty and human cooperation.

Law argues that regeneration involves the literal restoration of the divine image in humanity through the indwelling presence of Christ. Drawing heavily on patristic sources, particularly the Eastern tradition's understanding of theosis, he contends that the new birth is not merely forensic justification but an actual ontological change in which believers participate in the divine nature. The treatise traces this process from initial conviction through progressive sanctification, emphasizing that regeneration requires the death of the old self and the birth of a genuinely new spiritual nature. Law insists this transformation is both God's work alone and genuinely collaborative, requiring sustained human cooperation with divine grace through prayer, self-denial, and loving service.

The work has endured as one of the clearest Anglican articulations of regeneration as genuine spiritual transformation rather than legal declaration. Law's synthesis of Protestant emphasis on grace with Catholic mystical theology influenced later Anglican theology and contributed to evangelical revivals on both sides of the Atlantic. His integration of doctrinal precision with mystical depth offers resources for contemporary discussions of sanctification and spiritual formation. Readers seeking rigorous theology of regeneration will find Law's careful reasoning valuable, while those interested primarily in practical spirituality may find the work more abstract than his devotional writings. This treatise serves theologians and serious students of spiritual formation who want to understand the theological foundations underlying transformative Christian practice.
