Luke 12:2 - 'For there is nothing covered, that shall not be revealed; neither hid, that shall not be known.' Illustrate this biblical quote as a piece of digital art. The artwork should depict the transition from darkness to light, as a metaphor for the concept of truth coming to light. Include a symbolic representation of hidden knowledge being unveiled, in the form of a covered object being revealed in the middle of the illustration. This should be a digital artwork with vibrant colors that contrast and emphasize the theme.
