What It Says Nothing real can be threatened. Nothing unreal exists. Herein lies the peace of God. This is how A Course in Miracles begins. Knowledge is truth, under one law, the law of love or God.
Truth is unalterable, eternal and unambiguous.
It can be unrecognized, but it cannot be changed. It applies to everything that God created, and only what He created is real. It is beyond learning because it is beyond time and process. It merely is. The world of perception, on the other hand, is the world of time, of change, of beginnings and endings.
