The depiction of the verse Romans 7:22 - 'For I delight in the law of God after the inward man:' as an ornate manuscript illumination within an antique book. The visual metaphor can be that of a human silhouette (inward man), having an expression of pure joy and delight, looking towards a symbolic representation of the law of God - a celestial book or a radiant stone tablet containing the commandments. Create this using intricate detailing, luminous color palette, and stylized graphical elements typically found in classical manuscript illustrations.
