Taken at face value it is incredible that God is referred to our Everlasting Father because of Jesus. Scripture says that we are now adopted sons and daughter (2 Corinthians 6:18, John 1:12-13, Galatians 4:4-5, Romans 8:16-17, Psalm 10:16-18, Ephesians 1:5, Luke 20:36).
Lets talk about adoption for a second.
• In Roman tradition adoption was mostly used as a means of declaring and securing an heir.
• Adoption meant choosing the heir permanently. You could disown biological family, but once adopted you were a permanent member.
• All debts were released – they were wiped away as if they had never happened.
• Adoption was very expensive and a very serious ceremony.
• Strangers were rarely adopted into a family, usually a close friend or relative.
• Girls were rarely adopted.
• Slaves were rarely adopted, mainly freeborn children.
• It was rare that adoption would occur in the presence of a legitimate heir.
• 7 witnesses should be present at the adoption. Incase the adopted father died and there was a dispute, the other witnesses would step forward and bear witness to the rights of the child.
This gives us a deeper meaning of adoption as sons and daughters into the family of God, heirs and co-heirs with Christ; it makes it that much more meaningful and unusual. God sees us as equal, free, chosen, permanent children. The holy spirit is present at our adoption and bears witness of this miracle. We have a forever inheritance through our forever father.
