AYIGTG: Lesson #186; Salvation of the world depends on me.

If something requires our contribution to be complete, it would follow that completion depends on us. This is the logic of this Lesson #186. The bringing of the Heaven State to Earth cannot happen until we have brought this State of Being into our own life. Our part is essential in this plan of "Salvation." (Lesson #100) This is not "arrogance" to think our part is so important, because it actually is.  Salvation of the world depends on us, and we can exercise true humility when we accept that our Forgiveness adds to the greater whole of Atonement—for which this world is in great need.
