God already knows what you did. Confessing isn’t informing him. It’s agreeing with him.

Speaking it out loud is not for the benefit of whoever is listening. Nothing is being revealed. What changes is your own relationship to the fact, because an admission stops the enormous private effort of maintaining a different version. Agreement is the word for it: you stop arguing a case you knew was weak.

Pick the thing you have been describing to yourself inaccurately and say the plain version once, to yourself first. Then to one person if a person is owed it. Notice how much energy was going into the other version.
