Why is it significant that Paul addresses God as the Father of our Lord Jesus Christ?

By referring to God as the 'Father of our Lord Jesus Christ,' Paul signifies the unique and eternal relationship between the Father and the Son, emphasizing the Christian understanding of God as relational and covenantal. This title denotes not only intimacy but also authority and reverence. Furthermore, it underscores the Gospel's narrative in which Jesus, as the mediator, reconciles believers to the Father (Ephesians 2:18). In prayer, approaching God in the name of Christ acknowledges the access believers have through Him, affirming their identity as adopted children of God, which enriches the practice of prayer as an intimate communion with the divine.
