Can you tell me if this is correct?
Aorist indicative
The aorist does not describe a tense, but an aspect - namely, a punctual action. However, the aorist indicative is mostly used for the past tense. Therefore, it usually describes a point in the past that has occurred completely in itself, even if its effect continues into the present. This does not mean that something starts at a point in the past, but that something has arrived at a point in the past, that is completed, even if the result is still present. This means that the verb παρῆλθεν in 2 Corinthians 5:17 means that the old human nature has gone away once and for all in the past.
