Notice what's missing: no crucifixion, no atonement theology, no mention of sin requiring Christ's death. Jesus offers "Pardon" without explaining why pardon is needed or what it cost. This strips away the entire evangelical framework Dickinson grew up with—the anxious question wasn't "Will Jesus save me?" but "Have I felt conversion?"
The Phaeton reference is doing serious work. In Ovid, Phaeton begs to drive the sun-chariot, can't control it, and Zeus kills him to prevent cosmic disaster. Jesus essentially says: "I'm not Phaeton. My arms won't fail." It's a promise of competence—trust the driver, not the vehicle. This matters because Dickinson's Calvinist culture obsessed over whether you were elect—chosen by inscrutable divine will. Here Jesus just says get in, I've got you.
The poem's doubling—it prints the entire text twice—appears in some manuscripts. If intentional, it suggests the conversation repeats: the soul asks the same questions, gets the same answers, still hesitates. The dialogue might be recursive, happening over and over in the mind of someone who can't quite believe the offer.
