“In the Kingdom, there is no teaching or learning, because there is no belief” (ACIM)
“Without the idea of death, there is no world” (ACIM); there are no learned beliefs to unlearn. Without the electric light-wave thought mirrors erected there are none to take down. Without the idea of death to complete there is only the Relief of eternal Knowledge.
“Sacrifice is a notion totally unknown to God” (ACIM) God asks not His Son to put up or take down illusion, nor trade illusion for illusion.
Without the idea of death the concept of sacrifice has no place to exist. Knowledge of eternity is the Relief that dissolves all belief. To recall Knowledge, one surrenders the ego.
