This probably wouldn’t go as well as you might hope, this just gives them the opportunity to say something like “I know I’m not perfect which is why I’m thankful for the grace of my savior Jesus Christ”.
Its actually a feature of Christianity that you can sin as much as you want after you do the magic prayer, they are technically supposed to try not to, but the inevitable failure is due to man’s fallibility
More like they think everyone should feel guilt about it
