Jesus informs His disciples that He was bequeathing a gift to them that would guard their hearts and minds from trouble and fear.  He expresses that this gift was indeed HIS peace and explains it was not like the peace that the world has to offer, but would be a shield for their hearts and minds, much like a squad of soldiers protecting a town.  What an amazing gift our Lord and Savior gave to His disciples and now to us as His children!   We have a peace that protects our hearts and minds from being overwhelmed with any fears, any doubts, or any worries.  When we encounter tests, trials, or storms, we can be strong and courageous, allowing His peace to saturate our hearts and minds.
