Create an image following the genre of Art Nouveau that is themed around 'Mark 7:7' from the 'King James Bible'. The scene should be respectful and devotional towards Christianity, featuring symbolic elements such as a cross, a figure in prayer and divine light illuminating from above. Associated motifs and aesthetics of the Art Nouveau era, such as ornamental details, organic shapes and flowing lines, should be prevalent throughout the image. Keep in mind to observe a muted, yet warm color palette typical of the period. Do not include any text or words in the composition.
