The Christian life represents the integration of faith and practice; however, a persistent gap often exists between religious expression and daily conduct. This study addresses the need for a theological framework that guides believers toward a consistent expression of their identity in Christ. Focusing on 2 Corinthians 5:17, this research employs an exegetical method to examine the meaning of the expression en Christo (“in Christ”) and its theological implications. Through grammatical, lexical, and contextual analysis, the study reveals that being “in Christ” signifies a profound union that results in a radical transformation, described by Paul as becoming a “new creation” (kainē ktisis). This transformation entails not merely behavioral improvement but a comprehensive renewal of identity, character, and relational life. The findings affirm that the Christian life is fundamentally a life of ongoing renewal, in which the old self has passed away and a new life is actualized in Christ. This study contributes to practical theology by emphasizing the relevance of biblical exegesis for shaping a consistent faith identity and transformative daily living.
