How do we know that we are part of the family of God?

Membership in the family of God is not determined by earthly privileges but is a result of being born again through faith in Christ. As stated in John 1:12-13, those who receive Christ and believe in His name have the right to become children of God. This regeneration by the Spirit is essential for participation in God's family, as it transforms individuals, giving them a new nature that aligns with God's will. The assurance of being a part of this family comes from the work of Christ and the presence of the Holy Spirit in one's life, affirming their identity as a child of God, capable of calling Him 'Father.'
