Let us then at last arise, since the Scripture stirs us up saying: It is time now for us to rise from sleep (Rom. 13:11). And our eyes being open to the deifying light, let us hear with wondering ears what the Divine Voice admonishes us, daily crying out: Today, if you hear his voice, harden not your hearts (Psalm 95:7-8). And again, You who have ears to hear, hear what the Spirit says to the Churches (Rev. 2:7).
And what does he say? Come my children, listen to me, I will teach you the fear of the Lord (Psalm 34:12). Run while you have the light of life, lest the darkness of death seize hold of you (John 12:35).
Rule of St. Benedict, Prologue 8-13
