'Lord' in the Bible

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

but I did not see [any] others of the apostles except James, the brother of the Lord.

I have confidence in you in the Lord that you will think nothing different, but the one who is confusing you {will pay the penalty}, whoever he may be.

But [as] for me, may it never be [that I] boast, except in the cross of our Lord Jesus Christ, through whom the world has been crucified to me, and I to the world.

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