The Holy Spirit is a difficult topic. We can see many places in Scripture – Old and New Testaments – that document something about the Holy Spirit. However, organizing all of those references in a meaningful and productive way can be a challenge.
Nevertheless, it seems that understanding the Holy Spirit can be shaped and defined around four aspects:
We see each of these Holy Spirit “threads” carried through Scripture and fullfilled ultimately in the New Testement. God’s desire for His people to be holy remains today. His promise to dwell again with His people is fullfilled in the New Covenant and freely given to all baptized believers.
God’s power and His direct intervention into the affairs of mankind served two purposes:
A physical, visual demonstration of the ushering in of His promised “new covenant” and the gospel of Christ to the Jew first (Acts 2) and also to the Gentiles (Acts 10).
The need to confirm His word ended since His full and final word had been given to all mankind.
The tapestry of Scripture is a constant reminder of the “breadth and length and height and depth” of His knowledge and wisdom. The Holy Spirit is just one topic in this vast well of understanding. Hopefully these four aspects help your understanding of the Holy Spirit.
