Visualize a symbolic representation of Revelation 22:14 - "Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city." Emulate this in the style of stained glass art, with illuminated colors and intricate designs. The image should depict virtuous individuals following a path of commandments leading to a vibrantly colorful tree of life, behind which are the open gates of a majestic city.
