Get the heat and emotion out worry, and put cold, ruthless scrutiny onto the problem, and worry loses its power. When we are worried and filled with apprehension, we become panicky and are likely to see only gloom and failure. There isn\'t any situation so bad that it won\'t become a lot better when you think rationally - and spiritually - about it. God gives you the ability to think rationally about things by filling you with peace and faith.
