Insight is a function of the heart, not a function of the eyes.  God wants you to develop the ability to see from your heart what God has purposed for you to do and what He's purposed for you to have.  There are certain truths concerning the Kingdom, once they are revealed you move into a whole another dimension of walking by faith and not by sight while fulfilling the purpose for which God created you.  Min. Derrick B. Holder helps you come to know and comprehend these realities.
