Philippians 2:11
And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
The title "Lord" (Greek, Kurious) as Kittel's observes, means "one who has full authority." (7) In the Old Testament, God alone had "full authority" and filled both functions of Creator (Elohim) and Lord (Jehovah). Jehovah is used in connection with men with whom He has entered into some kind of covenant, starting with Adam in Genesis 2:7, and including Israel. Several redemptive characteristics and divine functions are associated with the sacred name Jehovah (Yahweh), including giving righteousness (Jeremiah 23:6), healing (Exodus 15:26), sanctification (Exodus 31:13), providing (Genesis 22:14), protection from enemies (Exodus 17:15), giving peace (Judges 6:24), and being continually present (Ezekiel 48:35). These functions can be assumed and/or delegated by persons having the authority. God has delegated many, if not all of these divine functions to Jesus Christ to share in as "Lord."
