Having a literal visual does more for the senses in making the understanding more virtually clear in the mind and is then received more powerfully into the minds reception or dismissal of the information. The impact was made for myself to know and see the Israelite people know what they are told but see the opposite in their approach. They then still walked into the water. That is the best part....they then STILL walked into the water. Then the promise was bestowed. The teaching elements that were with this were simple to the point and frankly I thought perfect for its purpose. Thank you.
