To oversimplify things a bit, Mormon notions of salvation are more consistent with Paul, while Evangelical notions of salvation are more consistent with deutero-Pauline ideas. In essence, Mormons, like Paul, believe that salvation is a future event; while Evangelicals, like deutero-Pauline authors, believe that salvation is a present event.
The deutero-Pauline letter Ephesians claims, “by grace you have been saved” (Eph 2:5, NRSV). The deutero-Pauline text Colossians agrees, and goes even further, explaining that you have died and have been raised already (Col 3:1-3). Saved in the past tense? Already raised? Yes, these texts consider that it is at baptism or some other event that has already brought about salvation.
