Many people begin, but few finish. And we, who are trying to behave as God's children, have to be among those few. Remember that only work that is well done and lovingly completed deserves the praise of the Lord which is to be found in Holy Scripture: 'better is the end of a task than its beginning'.
You may already have heard me tell this story on other occasions; but even so, I would like to bring it up again because it contains a very striking lesson. I was once looking through the Roman Ritual in search of the prayers for blessing the last stone of a building, obviously the most important stone, since it symbolically represents the hard and enterprising work of many people, who have persevered in the task throughout the long years of construction. To my surprise, I found that no such prayers existed, and I had to be satisfied with a benedictio ad omnia, that is, an all-purpose blessing. I must say that at first I just couldn't believe that there was such an omission in the Ritual, and I spent quite a while going over the index without finding what I wanted.
Many Christians are no longer convinced that the fullness of Life that God rightly expects from his children means that they have to have a careful concern for the quality of their everyday work, because it is this work, even in its most minor aspects, which they have to sanctify.
It is no good offering to God something that is less perfect than our poor human limitations permit. The work that we offer must be without blemish and it must be done as carefully as possible, even in its smallest details, for God will not accept shoddy workmanship. 'Thou shalt not offer anything that is faulty,' Holy Scripture warns us, 'because it would not be worthy of him.' For that reason, the work of each one of us, the activities that take up our time and energy, must be an offering worthy of our Creator. It must be operatio Dei, a work of God that is done for God: in short, a task that is complete and faultless.
