Silence is not only the indispensable condition for the development of the interior life, but it is also a sign of the maturity of virtue. When the interior life reaches a certain degree of development, it is marked by silence. In the beginning, we have some difficulty in speaking with God, but as our intimacy with God increases, our conversation with Him becomes easier, because His love provokes an inexhaustible source of loving words in our innermost soul. If this love continues growing until it reaches a certain degree, if our friendship with Jesus becomes more intimate and perfect, then words begin to fail us, because they seem impotent to express the sentiments of our heart. Little by little, words disappear, and our communication with God becomes the divine communication of silence.
–Luis M. Martinez (1881-1956)
