“For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!”” (Romans 8:15, ESV)
In the Roman world in which Paul was writing, adoption was a serious legal procedure. An adopted son was given all the rights of a natural-born child. Previous debts were cancelled. The old family relationships were severed. The adopted person took the adopting father’s name, inherited from his estate, and could not be unadopted; the relationship was permanent and legally binding. Paul chose this specific cultural institution to describe what God has done for believers through the Spirit.
The Spirit you received, Paul says, is not a spirit of slavery. A slave lived in the household, served the household, but had no standing in it. Everything the slave did was done in fear of what would happen if it was done wrongly. There was no rest in that, no security, no intimacy. Many believers live in exactly that posture with God, doing the right things to avoid the wrong consequences, never sure they have done enough, unable to settle into the relationship because the fear is always underneath.
The Spirit of adoption changes the question. You are no longer in the house as a servant performing for approval. You are in the house as a child. The word Abba is an Aramaic word for father, intimate and direct, the word a small child uses. It is not formal; it does not go through channels. It does not begin with a liturgy. It begins with a name, the name of someone you trust completely, and calls out to him.
This is the cry the Spirit produces in you. When you pray and something in you reaches for God not with dread but with belonging, that reaching is the Spirit of adoption at work. The intimacy you feel in genuine prayer is not something you manufactured; it is evidence of what has already been done. You have been adopted. The relationship is settled. The fear has no legal standing here.
You are not a servant performing. You are a child, coming home.
Prayer
Abba, Father. I say that today not as a formula but as the cry of someone who has been adopted and knows it. Thank you that I did not receive a spirit of fear. Thank you that I am not performing for your approval; I already have it. Holy Spirit, let the reality of my adoption settle into the parts of me that still relate to God like a servant afraid of getting it wrong. I am your child. I belong here. In the name of Jesus, Amen.
