Romans 8:15

For ye have not received the spirit of bondage. The time is referred to when they were born again, and entered the kingdom of God. They did not receive the spirit of bondage, of slavery to sin, so that they would obey its dictates, and thus be in fear of death. Instead, they received the Holy Spirit according to promise (Ac 2:38).

But ye have received the Spirit of adoption. The Spirit God bestows upon those who are accepted as his children. Paul was writing to the Romans, among whom the adoption of children, not their own by nature, was common. They would understand this to mean that those converted, or born again, are adopted as children of God; upon those thus adopted he bestows his Spirit; this Spirit in their hearts produces a loving trust that enables them to address God as Father.

Abba, Father. "Abba", Chaldee for "Father".
