Romans 8:15-17

Romans 8:15-17 The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship.  And by him we cry,  “Abba, Father.”  The Spirit himself testifies with our spirit that we are God’s children.  Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.

The Spirit that Saints receive does not make them slaves to the curse of the Law and cause them to live in fear again.  No, the Spirit brings Saints into being adopted into sonship.  As the previous verse pointed out Saints are adopted as children of God and the Spirit testifies this fact with our spirit. 

Praise God that Saints are heirs of God.
