The Groaning of the Spirit

There are times when words are not enough. How does God interact with our prayers that are too big for words?

"In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God." Romans 8:26-27
