The New Testament writers use spatial language and imagery to portray our relationship with God, speaking both about God or Christ in us, and us in them. Believers are also described as possessing and participating in divine qualities such as life and glory. Both aspects are prominent in John's Gospel and letters. However, outside the Pauline writings, union with Christ has hardly been addressed in New Testament scholarship. Dr. Clive Bowsher seeks to redress this balance in Life in the Son.In John's Gospel, the oneness of the Father and Son is described as the Father and Son being 'in-one-another.' Clive Bowsher's study shows that union with Christ in John's Gospel and letters is the in-one-another relationship of believers with the Father and Son by the Spirit - the intimate, loving, relational participation of the believer and God, each in the life, affections, ways and work of the other. Insightful and accessible, Bowsher's study also explores connections with the shape of sonship, and with covenant and the life of the age to come. This new volume in the NSBT series fills a significant gap in the literature and promises to be a blessing to pastors, preachers and scholars alike.
