What does it mean to be adopted as sons in Christ?

Adoption as sons in Christ signifies that believers are given a familial relationship with God, whereby we are regarded as His children. Ephesians 1:5 states that we are predestined for adoption as sons through Jesus Christ, which means we share in the privileges and inheritance of being part of God’s family. This status is not based on our worthiness but stems from God's loving choice and the work of Christ. Thus, believers can approach God as loving Father, receiving His guidance, protection, and grace throughout their lives.
