A little fear is good for it reigns in the ego and brings in caution. It keeps the image of the Lord God constantly in your mind and sight, preventing you from taking the wrong step. You are mindful of balance, your feet is firm on the ground and your head is not in the clouds but focused and clear in your direction. But too much fear destroys- it locks you in, preventing you from moving forward. Move out of excessive worries and fears, prevent it from becoming a stumbling block to your vision- else, you cannot live life wholesomely. . and you become a prisoner of your self created fears!
