Visualise an illustration inspired by a scripture, specifically Luke 11:9-10. Imagine the scene encapsulating the essence of asking, seeking and knocking. Show a diverse set of hands, belonging to people of different descents and genders, reaching out towards a luminous sky. Some hands are posed in a gesture of asking, others in searching, and a few knocking on an ethereal door. The illustration should convey a sense of spiritual hope and quest. Use vibrant colors and strong lines but keep it nuanced enough to encompass the subtlety and depth of the text. Create this in a digital art style with a modern aesthetic.
