What is the role of the Holy Spirit in prayer?

The role of the Holy Spirit in prayer is vital, as outlined in Romans 8:26-27. The Spirit not only helps us in our infirmities but also intercedes for us with groans that words cannot express. This means when we struggle to articulate our needs or desires, the Holy Spirit takes our incomplete petitions and transforms them into prayers that are aligned with God's purposes. This divine intercession ensures that our prayers are both effective and accomplished in the will of God, reinforcing the assurance that our spiritual needs are adequately met.
