Letting go of individual fears and insecurities changes you forever each time around. Living in the reality of life after those predispositions have been lifted off of us is why God created us as human, instead of equal with him. The true peace we feel in his presence in those moments helps us understand his nature, which we may never have felt without struggle; for it is through strife that we feel God's provision.
He provides us with a glimpse of heaven in small victories. When we conquer a fear, tear down a obstacle, or defeat an insecurity we feel a sense of clarity in an otherwise blurry world.
