When it all began, heaven was here on earth.
This physical and ordinary world, more than any of the higher spiritual worlds, was the place where the true essence of God's infinite light was found.
But humanity, step by step, faced the presence of God in its home, with the tree of knowledge, with a man who killed his brother, with all those things that humans do...
Because humanity cast her out, only humanity can bring her back. And that began with Abraham, who proclaimed the oneness of God throughout the world.
And it ends with us. Our generation will bring heaven back to earth.
