Let's start with Paul,
Rom 2:14 When Gentiles, who do not have the [Mosaic] Law [since it was given only to Jews], do instinctively the things the Law requires [guided only by their conscience], they are a law to themselves, though they do not have the Law. 15 They show that the essential requirements of the Law are written in their hearts; and their conscience [their sense of right and wrong, their moral choices] bearing witness and their thoughts alternately accusing or perhaps defending them [AMP]
Here, we see a most peculiar thing, something he looked at from another angle a few verses above: "you have no excuse or justification, everyone of you who [hypocritically] judges and condemns others; for in passing judgment on another person, you condemn yourself" [v. 1] Yes, we often quarrel, and in so doing, we reveal that we expect one another to know that we are duty-bound by first duties . . .
1: to, truth
2: to right reason
3: to warrant (and wider prudence)
4: to sound conscience
5: to neighbour, so too
6: to fairness, and
7: to justice,
. . .
xth: etc.
Nor, can we wriggle off the hook. For, when we attempt to deny or dismiss these as binding, we only manage to do so by bringing back the same duties by the side-door. If, instead we try to say, it's all an illusion, we are programmed to feel that way, again, by the side-door we are saying, there is a failed duty of warrant (as well, because this is so pervasive, we imply grand, pervasive delusion, self-referentially discrediting our own selves -- a form of, trying to condemn the other, only to indict our own selves).
So, we have to face the question, what sort of world-structure can ground such a seemingly strange state of affairs?
We can ponder:

As the above embed readily shows, there are many objections, but they all come back to depending on the same duties of warrant towards truth, etc.
So, we may freely infer, that reality is rooted in necessary being, and that such necessary being must be adequate to ground the fateful weight of ought. For which, there is a manifest best candidate, the good God.
Not a proof (the demand for which reflects the same first duties), but a structural reason to believe in God. Which then opens another paradigm-shift:
Heb 11:6 But without faith it is impossible to [walk with God and] please Him, for whoever comes [near] to God must [necessarily] believe that God exists and that He rewards those who [earnestly and diligently] seek Him.
For, as millions have found over the ages, through the gospel, God is not an abstract entity but a live, real, dynamic person who receives us with the open arms of a father, once we are willing to humble ourselves enough to penitently reach out to him. END
