The eagle can see a 3 inch fish jumping in a lake 5 miles away. Eagle like people can envision what most would miss. Vision for me is the capacity to allow God through His creative powers to create within us dreams and plans for the future that will help others and bring glory to Himself. The key seems to be in our responsiveness to act on His leadership. It is not that God desires to hold back the vision but rather our inability to believe Him for what He has placed in our hearts.
Vision is blurred at best without focus.
You may be able to see, but if this sight is not focused, you become handicapped. You can tell objects are there, but you can't quite make out what they are. You can see words on a page, but they are simply jumbled forms put together rather than comprehensible sentences and thoughts. When our vision becomes blurred, we go to an optometrist for a new set of glasses. Numbers chapter 13 gives us a paradigm a model an illustration of vision and focus.
