Life in the nightmare that you believe is reality is exhausting.   It  is filled with distractions that cause fear and anxiety, so that  many  feel they have to take precautions to protect themselves from  attack,  which they feel can happen when least expected.  They play out  numerous  scenarios in their heads in which they imagine themselves  setting up  barriers which will protect them from suffering, or from  which they  reach out to attack before they can be attacked. Living in  fear, and  preparing to defend yourselves or to attack others, takes  inordinate  amounts of your energy.
Every human is a beloved child of God, and to fear one another is   insane.  Your Father loves you all equally and wants only your   happiness, but if you keep fighting with, misleading, or betraying each   other in attack or defense, for whatever reason, you are in effect   blocking out and refusing to accept the abundance of Love that He holds   out to you constantly.
