From personal experience, possessing a conscience means that I become convicted within myself of wrong-doing without having to go to court to be convicted by a judge.
- Therefore you have no excuse, O man, whoever you are, when you judge another; for in passing judgment upon him you condemn yourself, because you, the judge, are doing the very same things. We know that the judgment of God rightly falls upon those who do such things. Do you suppose, O man, that when you judge those who do such things and yet do them yourself, you will escape the judgment of God? (Romans 2:1-3)
- When Gentiles who have not the law do by nature what the law requires, they are a law to themselves, even though they do not have the law. They show that what the law requires is written on their hearts, while their conscience also bears witness and their conflicting thoughts accuse or perhaps excuse them. (Romans 2:14-15)
The Conscience Is What Distinguishes Humans From Irrational Creatures of Instinct
