One Salvation, Three Stages: Be Saved, Being Saved, and Shall Be Saved offers a rich and holistic vision of the Christian life-rooted in the finished work of Christ, empowered by the Spirit in daily sanctification, and anchored in the hope of future glorification. This book explores the full arc of salvation, showing how justification, sanctification, and glorification are not isolated doctrines but an integrated journey of grace. It invites believers to see salvation not as a moment but as a lifelong transformation and a future certainty. With biblical clarity and practical depth, the book equips readers to walk faithfully in the tension of the already and the not yet-living with conviction, dependence, and expectancy. Whether you are a new believer seeking foundational understanding or a seasoned disciple desiring a fresh perspective, this book offers encouragement to live every day in light of the whole gospel. Through whole-life worship, community formation, and Spirit-empowered mission, readers will be inspired to embrace their salvation with confidence and live purposefully between the cross and Christ's return.
