Again and again Jesus stated that fear is the enemy of life. “Don’t be afraid; just believe” (Luke 8:50). “Do not be afraid little flock, for your Father has been pleased to give you the kingdom” (Luke 12:32). “Take courage! It is I. Don’t be afraid” (Matthew 14:27). Fear breeds a deadening caution, a holding back, a stagnant waiting until people no longer can recall what they are waiting for or saving themselves for. When we fear failure more than we love life, when we are dominated by thoughts of what we might have been rather than by thoughts of what we might become, when we are haunted by the disparity between our ideal self and our real self, when we are tormented by guilt, shame, remorse, and self-condemnation, we deny our faith in the God of love. When God calls us to break camp, abandon the comfort and security of the status quo, and embark in perilous freedom on the journey to a new Canaan, and we procrastinate out of fear, this represents not only a decision to remain in Haran, but also a lack of trust.
