Robyn J. Whitaker shows that the analysis of the rhetoric in the visions of God reveals in the book of Revelation, as the visions of God and of the Lamb serve as a means of persuasion of the author towards idols and worship. Through the rhetorical method of Ekphrasis Johannes revised its Jewish sources to visualize a God who seems otherwise spatially or temporarily absent. Thus it offers a verbal-visual image, which tries to fight the power of idols. By anchors the text within its religious and rhetorical context, Robyn J. Whitaker argues that its author in an ongoing discussion participated, whether writer or sculptor gods better represented if God would therefore best represented by words or images. Finally, John argued for the revealing power of words, and especially his text to experience as a way to God's presence and also to allow the worship of the divine.
