We are in a WAR AGAINST OURSELVES when we think "sin" is real. The mistakes we made do not make us "guilty." We are innocent regardless of any mistakes we made.
Only Innocence is real, and "sin" does not exist. Sinlessness is our real Strength. Guilt and Attack, the aspects of “sin,” make us weak.
The world of duality does not really exist even thought we are caught in its illusion. Our imagined "enemies" are our "saviours." We we see a sparkling beauty coming at us in a blessing.
Then we have no "war" with ourselves in this world of Heaven on earth that begins in our true Mind.
