Wir sind nicht nur deshalb sündig, weil wir vom Baum der Erkenntnis gegessen haben, sondern auch deshalb, weil wir vom Baum des Lebens noch nicht gegessen haben. Sündig ist der Stand, in dem wir uns befinden, unabhängig von Schuld.
We are sinful not only because we have eaten of the Tree of Knowledge, but also because we have not yet eaten of the Tree of Life. The state in which we are is sinful, irrespective of guilt. [Kaiser/Wilkins]
We are sinful, not only because we have eaten of the Tree of Knowledge, but also because we have not yet eaten of the Tree of Life. The condition in which we are is sinful, guilt or no guilt. [Hofmann]
This seems to be saying that eating from the Tree of Life will undo the sin of the Fall. But eating from the Tree of Life can't be our redemption, only something our redemption leads to, since, I assume, it isn't possible to get back into Paradise, and hence get to the Tree of Life to eat from it, without being redeemed first.
I suppose the question of guilt is waived because, being pure and innocent, Adam and Eve couldn't have known what they were doing when they ate the fruit of the Tree of Knowledge, since it was just that type of knowledge they could only get as a result of the act. They sinned, but they didn't know what they were doing, so there was sin without guilt. Sin and guilt are therefore two different things, and it's sin that will apparently be undone when we eat from the Tree of Life. This means we can eat from the Tree of Life and become free from sin, or at least absolved of sin, without necessarily ceasing to be guilty. So it's possible to be saved and guilty, and to sin in innocence.
