'Servant' in the Bible

Am I now using arguments to men, or God? or is it my desire to give men pleasure? if I was still pleasing men, I would not be a servant of Christ.

But if, while we were desiring to get righteousness through Christ, we ourselves were seen to be sinners, is Christ a servant of sin? In no way!

So the law has been a servant to take us to Christ, so that we might have righteousness by faith.

But now that faith is come, we are no longer under a servant.

There is no Jew or Greek, servant or free, male or female: because you are all one in Jesus Christ.

But I say that as long as the son is a child, he is in no way different from a servant, though he is lord of all;

So that you are no longer a servant, but a son; and if a son, then the heritage of God is yours.

Because it is in the Writings, that Abraham had two sons, one by the servant-woman, and one by the free woman.

Now the son by the servant-woman has his birth after the flesh; but the son by the free woman has his birth through the undertaking of God.

Now this Hagar is the mountain Sinai in Arabia, and is the image of the Jerusalem which now is: which is a servant with her children.

What then do the Writings say? Send away the servant-woman and her son; for the son of the servant-woman will not have a part in the heritage with the son of the free woman.

So, brothers, we are not children of the servant-woman, but of the free woman.
