“So then, brothers and sisters, we are debtors, not to the flesh, to live according to the flesh— for 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. For all 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 have received a spirit of adoption. When we cry, “Abba! Father!” it is that very Spirit bearing witness with our spirit that we are children of God, and if children, then heirs, heirs of God and joint heirs with Christ—if, in fact, we suffer with him so that we may also be glorified with him.” (Romans 8:12-17)
There are “stronger” scripture passages about the Spirit – outlining where the Spirit comes from and what the Spirit does in the lives of believers. But this is a good scripture passage to show how the Spirit is part of the Triune God. In the verses that follow (specifically verse 26) the writer of Romans says that the Spirit intercedes for us in prayer, when we do not know what or how to prayer, “with sighs too deep for words.” That is an instance of the “Spirit bearing witness with our spirit.”
Remember back on Wednesday, when Jesus told Nicodemus what is born of flesh is flesh, but what is born of “Spirit” is spirit. This is the unfolding of Jesus’ instruction to Nicodemus, of being “born again” and “being born from above”, and that the Spirit cannot be controlled or completely understood by humanity because it is a part of God, as Jesus is a part of God. Oh, beloved reader, how a triune understanding of God knits together all of this!
It is my hope and prayer that these three days of looking at the three aspects of God have given you something new to think about. And if your faith system already includes believing in the Trinity, I hope and pray that you have been blessed in looking at this part of your faith again. Selah!
