“I came for the salvation of the world.”
Strictly speaking, the world needs no saving. It was saved long ago.
When you change your mind, the images you see in the world change of their own accord, reflecting your new mindset. When you refocus and decide to only welcome the good and the lovely to come to you and reside within you, Creation in its fullness will become visible and experience-able. And then it is as if the world has been saved, saved from your delusional projections.
But Creation has been safe in Love all along. Thanks to your change of mind, you are now allowing a turn around that allows you to experience the reflection of Love in happy dreams that will lead you to the real world. And blissfully so!
