In Finding Assurance with Thomas Goodwin, Andrew S. Ballitch explores how deeply the doctrine of assurance of faith impacted Goodwin's life and how Christians can learn from him today. Doubt is a common Christian experience, and assurance of faith is a universal Christian desire. The Puritans were acutely aware of this reality--none more than Thomas Goodwin (1600-1680). Goodwin wrestled with doubt for seven years after his conversion. When assurance came, it was with joy and confidence that Christ was for him personally. His confidence fueled a life of holiness, service, and perseverance. Ballitch highlights how Goodwin's life informed his theology and vice versa, so that readers can experience for themselves the joys of assurance.
