Create a digital art interpretation of Mark 16:20, 'And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen.'. Illustrate an array of people from diverse descents and genders preaching in various locations across the world. The Lord is subtly present in the background, supporting and nodding in approval. Visual signs and symbols should be used to convey the message they are preaching. The overall mood of the image should be inspiring and uplifting, inviting contemplation.
