Sister Wendy Beckett says that "prayer is impossible without trust. We give our time and attention only and wholly because we believe that it is Jesus who prays within us. It is He who is united to His Father and we who life in Him--and do with that divine Father....Feeling or nonfeeling are equally unimportant. What matters is to stay at rest in the boat, down below sight level, while the wind that is the Holy Spirit bears us over the still waters to where the Father waits for us."
I have been having some days isolated in my room with a bad cold; maybe God just wanted me to prolong the retreat.
