The Spirit intercedes for us not in many words or long prayers, but with groanings, with little sounds like “Abba.” Small as this word is, it says ever so much. It says: “My Father, I am in great trouble and you seem so far away. But I know I am your child, because you are my Father for Christ’s sake. I am loved by you because of the Beloved.” This one little word “Abba” surpasses the eloquence of a Demosthenes and a Cicero.
