What does it mean to be a child of God by faith?

To be a child of God by faith, as described in Galatians 3:26, reflects our complete acceptance into God's family based on our belief in Jesus Christ. The term signifies a mature and privileged status, not merely as infants but as full-grown sons who inherit all the blessings of God’s kingdom. This identity is established by God’s sovereign will and love, indicating that our sonship is not based on our actions, but on Christ’s redemptive work and our faith in Him, which secures our eternal relationship with God.
