26Likewise the Spirit helps us in our weakness; for we do not know how to pray as we ought, but that very Spirit intercedes with sighs too deep for words. 27And God, who searches the heart, knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God. (Romans 8:26-27, NRSV)
When you can’t get the words to come out when the thoughts do not make sense in your own head, the Spirit knows what you need and intercedes.
We are never alone even when we think we are in a deep dark hole. God is always there and knows what we need.
