There is a certain method of practising the presence of God, by which, if the soul chooses, she may remain always in prayer, and constantly enkindled and inflamed with the love of God. This consists in realizing, in the midst of our occupations, that we are doing the will of God in each, and in rejoicing and being glad that it is so. -Rodriguez
It is said of St. John Berchmans that he never lost sight of the presence of God, that he practised it with rare facility and naturalness, and, what is more wonderful, he was free from absence of mind, so that he was always attentive to whatever he was doing, and ready and prompt to assist others.
St. Francis de Sales, for many years before his death, had scarcely any time for prayer, as he was overwhelmed with other occupations. One day, St. Jane Frances de Chantal asked him whether he had made his meditation. “No,” he replied, “but I am doing what is worth as much.” In fact, he endeavored to keep himself continually united with God, and he used to say that in this world we must make a prayer of works and activities. Thus, his life was a continual prayer, for he did not content himself with merely enjoying a delicious union with God in prayer, but equally loved to do His will.
