Death is one of humanity’s deepest realities, yet Scripture reveals it is neither accidental nor final. This in-depth biblical exposition examines the origin of death through sin, Christ’s victory over the grave, the believer’s hope beyond physical death, and the promise of resurrection. Grounded in both Old and New Testament teaching, this study equips believers to understand death through God’s redemptive plan and to live with faith, wisdom, and eternal perspective in the face of mortality.
