'Principle' in the Bible

Then what becomes of [our] boasting? It is excluded [entirely ruled out, banished]. On what principle? On [the principle of good] works? No, but on the principle of faith.

So now [if that is the case, then] it is no longer I who do it [the disobedient thing which I despise], but the sin [nature] which lives in me.

But if I am doing the very thing I do not want to do, I am no longer the one doing it [that is, it is not me that acts], but the sin [nature] which lives in me.

Therefore one must be subject [to civil authorities], not only to escape the punishment [that comes with wrongdoing], but also as a matter of principle [knowing what is right before God].

but [instead I would act on this goal] as it is written [in Scripture],“They who had no news of Him shall see,And they who have not heard [of Him] shall understand.”
