What does it mean to be adopted into God's family?

Adoption is a profound doctrine in Scripture, illustrating the believer's transition from being a child of wrath to becoming an heir of God. Galatians 4:5 states that through Christ, believers receive the 'adoption of sons.' This signifies not only a change in status but also a deep relational intimacy with God, whereby we can cry 'Abba, Father.' Such adoption grants believers the privileges of family, including spiritual blessings and an inheritance in the Kingdom of God. It emphasizes God's grace, whereby He befriends the unworthy and makes them joint heirs with Christ, establishing their identity in Him for eternity.
