This study examines the ethical significance of Joseph’s conduct in Genesis 39:1-23, with a particular focus on how his decisions were shaped by an enduring awareness of God’s presence. Employing a biblical-theological approach, grounded in the theoretical framework of covenantal theology and narrative ethics, this qualitative research analyses Joseph’s resistance to sexual temptation in Potiphar’s household and assesses its relevance to contemporary moral challenges in Nigeria.Through close textual analysis of Genesis 39 within its ancient Near Eastern background and canonical framework, this study reveals that Joseph’s moral integrity stemmed not from fear of consequence but from a theocentric conscience. His declaration, “How then could I do such a wicked thing and sin against God?” (Genesis 39:9), serves as a model for ethical conduct grounded in divine awareness.The findings of this research highlight the significance of Joseph’s story in addressing widespread moral decay in Nigeria, offering a timeless framework for youth mentorship and leadership accountability. The study concludes that moral renewal in Nigeria requires a return to God-centred ethics, with Joseph’s example challenging individuals and institutions alike to embrace integrity, discipline, and divine purpose in both private and public life.By drawing on biblical commentaries, African theological insights, and current socio-political literature, this study provides a nuanced understanding of the intersections between biblical ethics and contemporary moral challenges in Nigeria. The research contributes to ongoing discussions on the role of faith in shaping moral values and promoting integrity in leadership. Theoretical Framework: This study is grounded in the theoretical framework of covenantal theology and narrative ethics, drawing on the works of scholars such as Gordon Wenham and Walter Brueggemann. This framework provides a critical lens for analysing the narrative of Joseph in Genesis 39 and its implications for contemporary moral discourse.
