Here's one of the most beautiful stories that I came across a while ago. I have since kept it at heart because it speaks great volume in regard to fear and our comfort zone.
"The African Impala can jump to a height of over 10 feet and cover a distance of greater than 30 feet. Yet these magnificent creatures can be kept in an enclosure in any zoo with a 3 foot wall. The animals will not jump if they cannot see where their feet will land."
"Faith, is the ability to trust what we cannot see. And with faith, we are freed from the flimsy enclosures of life that only fear allows to entrap us."
