I am reading this pretty good book called "In a pit with a Lion on snowy day" and it has caused me to look at fears and failures (Lions) in a whole new light.
God is usually trying to use what we run from to either 1.) Bring glory to Him or 2.) Teach us something that will mold us into the image of His Son.
There is this part in the book where the author writes about being inoculated and how a little bit of a virus is given to you so that you can build up immunity to that virus.
He went on to say facing our fears and failures is kind of like being spiritually inoculated from whatever situation we find ourselves in. Think about it, how will God grow our trust in Him unless he places us in a situation that will cause us to rely on Him and learn to trust Him.
“The more we grow, the bigger God should get. And the bigger God gets, the smaller our lions get.” - Mark Batteron
