Verse..........................................

1.     You can do anything I ask.  I have asked you to perform miracles, and have made it clear that miracles are natural, corrective, healing, and universal.  There is nothing they cannot do, but they cannot be performed in the spirit of doubt or fear.  When you are afraid of anything, you are acknowledging its power to hurt you.  Remember that where your heart is, there is your treasure also.  You believe what you value.  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.
