Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are His. And, Let every one that nameth the name of Christ depart from iniquity (II Timothy 2:19).
The title Lord, when applied to Christ, is not merely a title of respect, but an acknowledgment of relationship. We belong to Him, just as bond servants (slaves) belong to their owners. He owns us, having bought (i.e., redeemed) us with His blood, and the distinguishing seal of His purchase is that His servants are expected to depart from iniquity.
Thus, whenever Lord is attached to His name, there is an implied confession of His Lordship in that particular area of life. For example, to be saved, one must confess with thy mouth the Lord Jesus (i.e., Jesus as Lord) and Believe on the Lord Jesus Christ (Romans 10:9; Acts 16:31). Following that, we are commanded: As ye have therefore received Christ Jesus the Lord, so walk ye in Him (Colossians 2:6).
Even in the mundane affairs of life, He is our Lord. Submit yourselves to every ordinance of man for the Lords sake (I Peter 2:13); Not slothful in business; fervent in spirit; serving the Lord (Romans 12:11).
Obedience to the Lordship of Christ is, of course, absolutely essential for a truly Christian and happy family. Wives, submit yourselves unto your own husbands, as unto the Lord. . . . Husbands, love your wives, . . . even as the Lord the church. . . . Children, obey your parents in the Lord. . . . And, ye fathers . . . bring [your children] up in the nurture and admonition of the Lord (Ephesians 5:22,25,29; 6:1,4).
As our text reminds us, Christs Lordship implies holiness and full submission to Him. Put ye on the Lord Jesus Christ, and make not provision for the flesh. . . . For whether we live, we live unto the Lord; and whether we die, we die unto the Lord (Romans 13:14; 14:8). HMM
