For those who are led by the Spirit of God are children of God.
For you did not receive a spirit of slavery to fall back into fear, but you received a spirit of adoption,
through which we cry, “Abba, Father!”
The Spirit himself bears witness with our spirit that we are children of God,
and if children, then heirs, heirs of God and joint heirs with Christ,
if only we suffer with him so that we may also be glorified with him. (Rom 8:12-17)
How important is the gift of the Spirit—for the Spirit is the proof that we are children of God! So we do not live in fear . . . rather, we live in the knowledge that we are truly children of God and heirs with Christ. For we too can say with confidence, “Abba, Father!”
