There is much beauty in both nature and man's creations in the world. I see even beauty in music that may be considered by some to be worldly. If you hear the Gershwin song "Embraceable You" arranged by Earl Wild for piano (Yeol-Eum Son played very well on YouTube), you must agree that it's beautiful. When I hear the melody, the excellent arrangement and beautiful interpretation by the artist, they lead my thoughts directly to God, the source of all beauty. The talents of the composer, arranger, and pianist as well as our sense of appreciation and enjoyment all came from the Lord.
Since beauty is delightful, I thought that we can be delightful ourselves too. By letting God make us pure and holy, we become delightful to him ~ what can possibly be more delightful?
