All my sermons are prepared in the presence of the Blessed Sacrament. As recreation is most pleasant and profitable in the sun, so homiletic creativity is best nourished before the Eucharist. The most brilliant ideas come from meeting God face to face. The Holy Spirit that presided at the Incarnation is the best atmosphere for illumination. Pope John Paul II keeps a small desk or writing pad near him whenever he is in the presence of the Blessed Sacrament; and I have done this all my life — I am sure for the same reason he does, because a lover always works better when the beloved is with him.
