As an adult, I don't ever ask for forgiveness. If I have done wrong, I apologize, I try to make amends, and I use the guilt and embarrassment as an motivation to avoid making that kind of mistake in the future. If the person I have harmed forgives me, that's great, but it is not appropriate to burden them with the job of making me feel relieved. It is on me, as a grownup, to accept what I did.
That makes sense, right?
So why would you ever ask a third party, let's say God, to forgive you? What for? That's baby stuff. Babies want to be forgiven. Adults deal.
And moreover, how can you respect people who need forgiveness for sins? How can you trust people who think that they have been magically purified by praying to their deity?
This truly baffles me. Can this be explained?
