How do we know the Holy Spirit is our helper in prayer?

In Romans 8:26-27, Paul explains that the Spirit helps us in our weakness, especially in the area of prayer. This implies that even when we feel incapable of praying or are unsure of what to ask for, the Holy Spirit is actively interceding for us. His groanings represent our deepest needs, effectively communicating them to God. This assurance emphasizes that prayer is not just a human endeavor but one that is significantly empowered and animated by the Holy Spirit, assuring us that our prayers are heard and understood.
