What does the Bible say about the Holy Spirit's role?

In John 14:25-27, Jesus conveys the essential role of the Holy Spirit as our Comforter, a vital presence that not only teaches but also brings to remembrance everything Jesus has said. This aligns with the relational aspect of the Trinity, where the Holy Spirit functions uniquely in our lives. His teaching leads to a deeper understanding of Scripture and the realization of our dependence on Christ's redemptive work. The Holy Spirit consistently guides believers into all truth, illuminating their hearts and minds.
