This exercise has been the most helpful in my walk. While attending a conference the audience was presented with an example of Peter walking on water. The challenge was to step out of our comfort zone and allow Him to show us our weaknesses. When you do give permission for this challenge, do not be surprised that He now has permission from you to show you. He will put you through some helpful testing to strengthen you in those areas. Once you feel you have past that testing, He will change it all up and give it to you in another form. You can always say UNCLE or ask for revelation in other areas.
