Quote from ACIM Text Chapter 8, Section 6 - The Treasure of God.

The world can add nothing to the power and the glory of God and his holy sons, but it can blind the sons to the Father if they behold it. You cannot behold the world and know God. Only one is true. I am come to tell you that the choice of which is true is not yours to make. If it were, you would have destroyed yourself. Yet God did not will the destruction of his creations, having created them for eternity. His will has saved you, not from yourself but from your illusion of yourself. He has saved you for yourself.
