Land/soil (adamah) is part of God's creation and the source of much of our prosperity. People do not own the land so much as lease it from God, especially in the case of ancient Israel. Sinning against God might involve improperly using His land or using its bounty for sinful ends. The original sin of Adam is manifested in the land by the land being corrupted by this sin as well, producing thorns and thistles. God's blessings in this world are still present, but evil is now present beside them. Job sees evil in his own life despite his righteousness, and we see it too despite us being made righteous by God. We hope to enter into Eden once more to be freed from the corruption of this world.
