Romans 8:15
14 For all who are led by the Spirit of God are the sons of God. 15 For you did not receive the spirit of slavery leading again to fear, but you received the Spirit of adoption, by whom we cry, “Abba, Father.” 16 The Spirit himself bears witness to our spirit that we are God’s children. 17 And if children, then heirs (namely, heirs of God and also fellow heirs with Christ)—if indeed we suffer with him so we may also be glorified with him.
2 Timothy 1:7
6 Because of this I remind you to rekindle God’s gift that you possess through the laying on of my hands. 7 For God did not give us a Spirit of fear but of power and love and self-control. 8 So do not be ashamed of the testimony about our Lord or of me, a prisoner for his sake, but by God’s power accept your share of suffering for the gospel.
Notes and References
"... In this text in 2 Timothy there is a clear connection with the language of Romans 8:15. The suitability of a text from Romans for instructing Timothy need not be questions (Rom 16:21). Both texts are “Spirit” texts, though, as we will see, the situation in which we find Timothy in 2 Timothy requires a reshaping of the earlier teaching. It is in the reshaping of the text, I would argue, where the evidence for conscious intertextuality emerges. The basic observation to be made from this comparison of translations is that NIV and NRSV treat the reference to “spirit” as a reference to the human spirit. In my judgment, this cannot have been intended in either Romans or 2 Timothy in view of the dominance of the Holy Spirit in each case. The TNIV has corrected the NIV; and the GNB’s theological reading of the texts in question shows good Pauline instincts. ..."
