Our free Will allows Us to believe what We want the truth to be.

However Our Will can not change Truth, Truth is changeless. That's why it is Truth.

If something changes then it's not Truth. This is a world of constant change.

Our Creator is watching the Creations "play" in their dreamworld.

The Creator knows We are doing this, like a parent watching their children play with their toys.

But cannot know exactly what We are doing, because this world is impossible.

That's why We were given the Holy Spirit.

The Holy Spirit is Our guide from this dream/illusion back to Truth.

I'm sure there are other names, but Holy Spirit is the one I know.
