'Words' in the Bible

To whom we gave way not even for an hour; so that the true words of the good news might still be with you.

But when I saw that they were not living uprightly in agreement with the true words of the good news, I said to Cephas before them all, If you, being a Jew, are living like the Gentiles, and not like the Jews, how will you make the Gentiles do the same as the Jews?

Is the law then against the words of God? in no way; because if there had been a law which was able to give life, truly righteousness would have been by the law.

So then am I no longer your friend, because I give you true words?
