'Lord' in the Bible

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

because I hear of your love and of the faith which you have toward the Lord Jesus and toward all the saints;

no longer as a slave, but more than a slave, a beloved brother, especially to me, but how much more to you, both in the flesh and in the Lord.

Yes, brother, let me benefit from you in the Lord; refresh my heart in Christ.

The grace of the Lord Jesus Christ be with your spirit.
