How does the Holy Spirit help Christians in prayer?

The intercessory role of the Holy Spirit is clearly articulated in Romans 8:26-27, which states that He helps our weaknesses and intercedes for us with groanings that cannot be uttered. This underscores that our prayers are aided by the Spirit's understanding of our needs and God's will, making them acceptable before the Father. Without the Holy Spirit's guidance in prayer, our human limitations would hinder effective communication with God. The assurance that He intercedes for us strengthens the believer's reliance on God's grace and mercy.
