“Just as men spontaneously praise whatever they value, so they spontaneously urge us to join them in praising it. ‘Isn’t she lovely? Wasn’t it glorious? Don’t you think that magnificent?’ The Psalmists in telling everyone to praise God are doing what all men do when they speak of what they care about.
“My whole, more general, difficulty about the praise of God depended on my absurdly denying to us, as regards the supremely Valuable, what we delight to do, what indeed we can’t help doing, about everything else we value. I think we delight to praise what we enjoy because the praise not merely expresses but completes the enjoyment; it is its appointed consummation. It is not out of compliment that lovers keep on telling one another how beautiful they are; the delight is incomplete till it is expressed. … This is so even when our expressions are inadequate, as of course they usually are. But how if one could really and fully praise even such things to perfection—utterly ‘get out’ in poetry or music or pain the upsurge of appreciation which almost bursts you? Then indeed the object would be fully appreciated and our delight would have attained perfect development. The worthier the object, the more intense this delight would be.” —C.S. Lewis, in Reflections On The Psalms
