You aren't terrified of snakes, but you exercise appropriate caution. You see blue skies, birds, squirrels, a deer, breath taking scenes, and all the glory of spring time. You constantly take in the whole scene around you, and love it. The two of you were together the whole time on the same trail in the same woods in the same situation sharing the same experience. The fear that produces anxiety, worry and distress is a spiritual liability.
Faith can exist and grow where there is such fear.
However, faith exists and grows in the presence of such fear only if the fear drives to person to greater dependence on God. If the fearful person becomes increasingly prayerful and involved in study as he or she clings to God, faith grows. As a general rule, two things are true. As faith grows, fear dies. As fear grows, faith dies.
