'Moral' in the Bible

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

I am using a human analogy because of the weakness of your flesh. For just as you offered the parts of yourselves as slaves to moral impurity, and to greater and greater lawlessness, so now offer them as slaves to righteousness, which results in sanctification.

For I do not understand my own actions [I am baffled and bewildered by them]. I do not practice what I want to do, but I am doing the very thing I hate [and yielding to my human nature, my worldliness—my sinful capacity].
