15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption,(His children) whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Romans 8:15 Contemporary English Version
God's Spirit doesn't make us slaves who are afraid of him. Instead, we become his children and call him our Father.
