What theological concept explains humanity's condition post-fall?

The theological concept that explains humanity's condition post-fall is best described by the idea of the guilt and corruption of human nature. This concept arises from the belief that after the fall of Adam and Eve, humanity was fundamentally changed in its nature and standing before God. The fall introduces sin into human experience, leading to both moral and spiritual corruption that affects every aspect of human existence.

This understanding emphasizes that, due to sin, humans possess a nature predisposed to wrongdoing and a separation from God. It suggests that not only is humanity guilty before God because of the original sin, but also that this guilt results in an inherent corruption, which means individuals struggle against sinful tendencies throughout their lives.

In contrast, concepts such as the continuation of human perfection, original righteousness, or the innate ability to choose good do not adequately capture the implications of the fall. These ideas suggest an unblemished state or an ability to consistently choose good, which is inconsistent with the theological understanding of humanity's post-fall condition.
