When Adam & Eve sined, mankind lost his inheritace in the kindom of god. But god  loved man, who was made in his own image, and sent his only begotten son to this world, and he died on the cross to give us eternal life.

If any man accepts Jesusus and is born again we become son's of god and will once again inherit the kindom of god. The kindom of god is governed by kindom priciples and not by worldy principles
