Life's circumstance has taken a hold on many of us to the point where we stop believing. It is sad that too often we allow situations, people and things to define 'who we are'. In some cases it so extreme that we begin to question God's character...His faithfulness. If you continue to allow your confidence to be salvage by life circumstance or changes you may be giving the enemy an opportunity to step in. Of course he has no good intention for you. A lack of confidence in life, in yourself could be demoralizing when you desire to do something, when you want to make it, but you feel unable to because of how you feel inside. Hence, it limits your progress in life.
