How does the Bible describe the role of the Holy Spirit?

In Romans 8:26, it states, 'Likewise, the Spirit also helpeth our infirmities.' The Holy Spirit plays a crucial role in the life of the believer by providing assistance and guidance in prayer and spiritual matters. The Spirit intercedes for us even when we do not know how to pray as we ought, working within us to align our hearts with God's will. Moreover, the Spirit empowers believers to live in accordance with the teachings of Christ, fostering a life characterized by spiritual growth, sanctification, and a deeper relationship with the Father.
