According to Michael Ward (author of Planet Narnia) Psalm 19 was one of C. S. Lewis’ favorite Scriptures:
Lewis described Psalm 19 as the greatest poem in the book of Psalms and one of the greatest lyrics in the entire world. The apostle Paul quotes Psalm 19 and says that what the heavens speak is “the word of Christ” (Romans 10:17-18, NIV). ~ The Narnia Code page 146
Psalm 19
The heavens declare the glory of God, and the sky proclaims the work of His hands.
Day after day they pour out speech; night after night they communicate knowledge.
There is no speech; there are no words; their voice is not heard.
Their message has gone out to all the earth, and their words to the ends of the inhabited world. In the heavens He has pitched a tent for the sun.
It is like a groom coming from the bridal chamber; it rejoices like an athlete running a course.
It rises from one end of the heavens and circles to their other end; nothing is hidden from its heat.
The instruction of the LORD is perfect, reviving the soul; the testimony of the LORD is trustworthy, making the inexperienced wise.
The precepts of the LORD are right, making the heart glad; the commandment of the LORD is radiant, making the eyes light up.
The fear of the LORD is pure, enduring forever; the ordinances of the LORD are reliable and altogether righteous.
They are more desirable than gold – than an abundance of pure gold; and sweeter than honey – than honey dripping from the comb.
In addition, Your servant is warned by them; there is great reward in keeping them.
Who perceives his unintentional sins? Cleanse me from my hidden faults.
Moreover, keep Your servant from willful sins; do not let them rule over me. Then I will be innocent, and cleansed from blatant rebellion.
May the words of my mouth and the meditation of my heart be acceptable to You, LORD, my rock and my Redeemer.
Psalm 19:1-14
He is the radiance of His glory, the exact expression of His nature, and He sustains all things by His powerful word. After making purification for sins, He sat down at the right hand of the Majesty on high. Heb 1:3
Addendum:
If you have an interest in C. S. Lewis’ “Space Trilogy” more correctly referred to as the Ransom Trilogy, I recommend a book by Christiana Hale – Deeper Heaven: A Reader’s Guide to C. S. Lewis’s Ransom Trilogy. See also our article: Time to Visit That Hideous Strength Again
