What we call attack, is actually retreat.
God cannot be attacked. When you try to attack God, if you were to go punch God in the face, guess what happens? Every effort you make to throw your fist forward, it's as though your fist goes nowhere, and instead the rest of your body is pushed backwards. I'm just using this as a 'visual' to make my point.
Metaphysically, energetically, mentally, any form of attack is really a withdrawal of cowardice and fear, a recoil into darkness and AWAY from love.
How can love be attacked when attack is a movement away from love?
This is why we are immortal.
Immortality cannot be attacked. Nothing real can be threatened. Illusions cannot assail the Kingdom of Heaven.
This isn' just information. This is the composition of reality.
Love is, and ego is not.
Love is, and attack is not.
Viciousness and terror goes hand in hand with being terrified. Torrorism IS fear.
Everything the ego does looks like one thing - attack - outward expression and forward motion towards harm - but is in fact the exact opposite - recoil away from and withdrawal from love.
Love is therefore always perfectly protected.
"The Kingdom is perfectly united and perfectly protected, and the ego will not prevail against it. Amen" - ACIM
This is why you cannot be really hurt. This is why nobody else can do anything to you. This is why you are permanently invulnerable. This is why you have IMMORTALITY and can never die.
There is no death, silly.
