In the last part of this series, I mentioned that Romans 10:9 has a condition represented by the aorist subjunctive with ean with a result the future indicative of sodzo. Since that time, I looked up the same construction varied only by the aorist subjunctive with an, instead of ean. There are four examples of these with the future indicative of sodzo as the result. That enlarges our sample size to 9 examples, and it also gives us some helpful information in understanding Romans 10:9, 13, which greatly buttresses the pre-justification "confess" and "call" view.
If you look at the two charts carefully, you will see a pattern of usage here. When talking about salvation and expressing a condition for salvation with the aorist subjunctive with ean or an, the result is in this lifetime, not something eschatological. I believe they are immediate results. We also can see the aorist relates action that is completed at a point in time, debunking that "call" and "confess" are some post-justification lifestyle espoused by Thomas Ross.
Speaking of the Aorist Subjunctive versus the Present Subjunctive, A. T. Robertson comments on this in his classic, huge grammar (pp. 848, 849): "The contrast between point and linear action comes out simply and clearly here. It is just that seen between the aorist and the imperfect indicative." For those who don't know Greek, when Paul writes "confess with thy mouth," he is speaking of an act that is point action. He does the same in v. 13 when he says, "call upon the name of the Lord." This isn't a durative or linear action in v. 9 and then in v. 13, but punctiliar action. This kind of action does not fit with a lifestyle of confessing and calling. It emphasizes a point in time "confess" and "call" that is corresponds to a pre-justification act.
It is true that on occasion "shalt be saved" is speaking of eschatological salvation, essentially glorification. It is found that way in Romans. However, in these conditional sentences, that isn't what is being communicated, which is why the conditional sentences were used here. These conditions mark a non-eschatological salvation, one that occurs upon the conditions being met, which are not durative conditions, but point-in-time conditions.
