Let us then rise at length, since the Scripture arouse us,
saying: “It is now the hour for us to rise from sleep” (Romans 13:11);
and having opened our eyes to the deifying light, let us hear with awestruck
ears what the divine voice, crying out daily, does admonish us, saying:
“Today, if you shall hear his voice, harden not your hearts” (Psalm 94[95]:8). And again: “He that hath ears to hear let him hear what the
Spirit says to the churches” (Revelation 2:7). And what doth He say? “Come,
children, hearken unto me, I will teach you the fear of the Lord” (Psalm 33[34]:12). “Run whilst you have the light of life, that the darkness of
death overtake you not” (John 12:35).
