Paul is teaching us that Holy Spirit aids us by praying on our behalf with sounds that we may not understand but are perfectly clear to God. This practice, known as praying in tongues, involves the Holy Spirit using our voice to communicate God’s will. These prayers align perfectly with God’s desires, ensuring they are effective and not misguided. Through the Holy Spirit’s intercession, God works everything in our lives for our ultimate good, even if not everything is inherently good. This divine assistance is available to those who follow God’s general commands and specific instructions for their unique calling. Praying in the spirit not only helps us navigate our lives but also strengthens our faith.
