Reflect the verse 2 Corinthians 5:2 - 'For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven' visually in a digital art format. Show a range of diverse individuals, all appearing contemplative and hopeful, progressively transforming their earthly attire into celestial constructs, symbolizing their heavenly domicile. Incorporate an overall ethereal and serene aesthetic, with luminescent hues, ethereal shapes, and abstract constructs for the celestial imagery. Characters should include a Middle-Eastern woman, a South Asian man, a Black woman, and a Caucasian man.
