I admire visionaries.  To me, a visionary can see just beyond my horizon.  It really does not matter how far; just so that it is farther than where I can see.  With visionaries, I find myself stretched, pulled, and tugged into something greater than my sight.  When that happens, the value I place on the words, insight, and picture is simply beyond measure.  What else can one say?  If one wants to go beyond, who else is there to lead?  If one is willing but struggles with limited eyesight, is there a any reason to debate what you do not have and cannot attain on one's own?
Visionaries, be it an individual, community, company, or occasionally even a nation, do things that others cannot and will not. 
They invest in the future and in what they see that others do not.  Their resources go with their visions.  They put themselves out where others can question, ridicule, and even try to destroy.  They are often stubborn in their sight, willing to see what others deny.  They also inspire and ultimately give others a real sense of what they could only imagine in their best dreams.
When a visionary is anchored in truth, they inspire and lead.  The strength and power of truth takes their vision to places even they cannot imagine.  Great buildings, powerful ideas, and even spiritual Hope are all the result of great visionaries.  One man's voice has echoed across the ages.  Because, “being also a prophet and knowing that God had solemnly sworn that a descendant of his would rule his kingdom, seeing far ahead, he [David] talked of the resurrection of the Messiah-'no trip to Hades, no stench of death.'”  (Acts 2.30)  David shared his vision of what was to come and it inspired generations that followed.
God offers visions to those willing to see though Divinity's eyes.  The offer is not for the faint of heart.  Hardship often comes with the new sight.  For those who respond, others will offer thanks and follow.  It is a calling worthy and available to all.
