"Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered."
Sometimes it is hard to know just *how* to pray, or for *what* to pray. This is a "weakness," but it is not a debilitating one. The reason: the Holy Spirit Himself "makes intercession" for us. When I have a hard time knowing how to pray, I usually try to discern what the main and pressing *concerns* are, that are on my heart.
I then try to bring those to the Lord, and to ask for strength and wisdom. In any case, it is better to *try* to pray, than to leave off praying altogether (because it is often so difficult). God is pleased with our faith-driven efforts, even though they are sometimes paltry. Thankfully, the Holy Spirit "fills in the gaps."
