Father Apostoli said a story in a program in ewtn, I will paraphrase, as I don’t remember exactly. He said that there was a Priest that was very committed to God, and Jesus appeared to Him, but at that instance, was at the time when he had to feed some poor people. And the priest was thinking what he should do, because he was afraid that if he went away the apparition would disappear. But he decided he needed to attend his people, his duty. So he went to act his duty, after that he came back, the apparition was there, and Jesus told him that he chose wisely, because if he would have chose to stay because of the apparition he would have disappear.
I thought about this when reading:
{There is another inward kind of prayer without ceasing, which is the desire of the heart. Whatever activity you happen to be engaged in are doing, if you only long for that Sabbath then you do not cease to pray. If you do not want to pause in prayer then never pause in your longing.
Your continuous desire is your continuous prayer. If you cease to desire than you will have fallen silent in your prayer. Who are those who have fallen silent? Those of whom it is said Because iniquity will abound, the love of many will grow cold.}
The post by hazcompat, which I really liked.
So our prayers continue with our non-ceasing desire to please God, in our prayers, in our duties, in our life. As in fact life itself is given by God, and while we are graceful for the things given and trying to do His will in faith without ceasing, then this is our continuous prayer.
