There are times in history when the dark drums of God can barely be heard amid the noises of this world. Then it is only in moments of silence, which are rare and brief, that their beat can be faintly discerned. There are other times. These are the times when God is heard in rolling thunder, when the earth trembles and the treetops bend under the force of [God’s] voice. It is not given to men [and women] to make God speak. It is only given to them to live and to think in such a way that, if God’s thunder should come, they will not have stopped their ears.
