"The promise"
It isn't a promise, it is a statement of fact, a completed action without regard to the past, present or future. When you trusted you were sealed, period. Nothing else is necessary for justification and regeneration. Everything else is working out what one is, saved to the utter most. Now one can get on with the business of working out that salvation with the new life that has been given without having to worry about whether the redemption took or having confessed enough to the professional.
In the gospel of Blue Duncan? I'll wait for the movie, thanks.
