What kind of circumstance did G-d create in which to test this soul so that the soul would have to literally work to get to the World to Come? G-d wants us to become aware that He is One, that it is his being which is the substrate of all reality and all existence. There is nothing outside of G-d. He has taken His unity and fragmented it, with many variations. If you mistake your own powers of creation as divinity, then in the World to Come you have nothing. But if you realize that only G-d has divinity, then your soul will have eternal ecstasy in the World to Come.
