Romans 8:26-28 NRSV
Likewise 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. And 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.
We know that all things work together for good for those who love God, who are called according to his purpose.
