As a Reformed theologian, I agree that all art is frivolous; however, as an artist, I believe that the process of artmaking is never frivolous. Whether or not the artist intentionally creates a religious piece, by creating, the artist is invited to imitate the God of all creation: In the beginning was creativity, and the creativity was with God, and the creativity was God. All things came into being through the mystery of creativity; apart from creativity nothing would have come into being.
