Romans 8:12-17

12So then, brothers, we are debtors, not to the flesh, to live according to the flesh. 13For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live. 14For all who are led by the Spirit of God are sons of God. 15For 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!” 16The Spirit himself bears witness with our spirit that we are children of God, 17and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.

We are no longer slaves to fear; we are children of God

1 John 3:1

1See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him.
