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

In Galatians 3:26-29, Paul explains that all believers, regardless of their background, become children of God through faith in Christ Jesus. This radical inclusion transcends cultural and social boundaries, indicating that faith in Christ unites people into one body, the church. As children of God, believers inherit the promises made to Abraham, which include spiritual blessings such as forgiveness and eternal life. This relationship is established by faith, which is both a gift and a profound union with Christ, ensuring that believers are regarded as heirs according to the promise.
