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

According to Romans 8:26-27, the Holy Spirit plays a crucial role in our prayer life by helping our infirmities. This passage indicates that we do not always know what to pray for as we ought, but the Spirit itself intercedes for us with groanings that cannot be uttered. This help is particularly significant when we are burdened by our physical and spiritual weaknesses, allowing us to communicate with God more effectively. The Spirit’s intercession is based on the mind of God, ensuring that our prayers are aligned with His divine purpose.
