'Lord' in the Bible

Grace to you and peace from God the Father, and our Lord Jesus Christ,

But I say that so long as the heir is a child, he is no different from a bondservant, though he is lord of all;

I have confidence toward you in the Lord that you will think no other way. But he who troubles you will bear his judgment, whoever he is.

But far be it from me to boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.

From now on, let no one cause me any trouble, for I bear the marks of the Lord Jesus branded on my body.

The grace of our Lord Jesus Christ be with your spirit, brothers. Amen.
