Craft the scene from the biblical context where a crowd of people are gathered in a serene desert landscape, attentively listening to a humble, dignified figure preaching, who might be interpreted as John the Baptist based on his simple attire and a staff. Surround this figure with radiant nimbus reflecting divinity. Also, depict a symbolic representation of 'the kingdom of heavens' as a vibrant, majestic, transcendent realm above, shimmering with surreal hues. Render this entire solemn scene in a style resembling watercolor paintings of the late 1800s. The art must express a heartfelt sense of devotion to Christianity.
