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.
