Why It Is Not Too Late To Repent And Turn To Christ

[Esquilax]

The action can be objectivaly best ACCORDING to a set of values.
If you want to win a game of chess there are best moves. If you want to lose worst moves become best instead.

The values are not objective. Which means actions are not objective either because they are governed by values.

If you are sick and you value being healthy going to a doctor is objectively good. But you are not objectively ought to be healthy. It's just what you prefer.

I guess, though I would suggest that, on balance, those that prefer being sick over being healthy don't tend to live very long to be a part of the process of determining those values.

And frankly, I think it's pretty far-reaching to be using examples of people working objectively against their own self interest.
