Romans 8:26-28

"The Spirit helps us in our weakness.  We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express.  And he who searches our hearts knows the  mind of the Spirit, because the Spirit intercedes for the saints in accordance with God's will.  And we know that in all things God works for the good of those who love him, who have been called according to his purpose."
