“How many times have we asked and not received, knocked and found a closed door?.. Prayer always transforms reality: if things around us do not change, at least our hearts are changed. Jesus promised the gift of the Holy Spirit to every man and woman who prays … Nothing is more certain: the desire for happiness we all carry in our heart will be fulfilled.”
