You saw it quite clearly: while so many people do not know God, he has looked to you. He wants you to form a foundation stone, an ashlar, on which the life of the Church can rest.
Meditate on this reality and you will draw many practical consequences for your ordinary behaviour: the foundation stone — hidden and possibly rather dull — has to be solid, showing no weakness. It has to serve as a support for the building... If not, it remains isolated.
