This volume provides a detailed examination of Paul's use of the phrase 'Christ in You' and highlights its importance for better understanding Paul's eschatological thought. Having previously received relatively little scholarly attention, the expression 'Christ in You' has often been viewed as synonymous with the phrase 'in Christ.' Barcley recognizes a distinction and argues that Paul uses 'Christ in You' specifically to emphasize the proper functioning of faith in life. 'Christ in You' indicates that believers have undergone a spiritual transformation, fully incorporating Christ into their lives. This study will be of value to religious scholars, pastors, and anyone with an interest in New Testament thought.
