The Scroll of God Starting with the inspired Scriptures, sometimes Christians have reached further back in cosmic memory, as it were, to speak of nature itself as a sort of book, a sacred scroll in which God is revealed. Those medieval writers, expressing a synthesis typical of their time, found this idea of a double revelation in the words of the Bible itself. These two revelations are the topics of the two halves of this psalm. First, nature, given us by God that we may know him.
Day speaks the word unto day, and night unto night proclaims the knowledge.
That is to say, there is a message for us from God, inscribed in the structure of Creation. The testimony of the Lord is sure, giving wisdom to little ones. The judgments of the Lord are right, rejoicing the heart. The commandment of the Lord is bright, enlightening the eyes. The fear of the Lord is holy, enduring for ever and ever.
