If you are afraid, you are valuing wrongly. Your understanding will then inevitably value wrongly, and by endowing all thoughts with equal power will inevitably destroy peace. That is why the Bible speaks of “the peace of God which passeth understanding.” This peace is totally incapable of being shaken by errors of any kind. It denies the ability of anything not of God to affect you. This is the proper use of denial. It is not used to hide anything, but to correct error. It brings all error into the light, and since error and darkness are the same, it corrects error automatically.
