This influential Christian work is based on Watchman Nee’s expository messages on the Book of Romans, particularly chapters 6–8. It discusses the spiritual realities of Christian living—focusing on identification with Christ’s death and resurrection, walking in the Spirit, and freedom from sin. It emphasizes that the "normal" Christian life is not one of striving but one of resting in what Christ has already accomplished.

Key themes include spiritual union with Christ, sanctification, surrender, grace, and victorious living through faith.
