And [that] every tongue should confess that Jesus Christ [is] Lord, to the glory of God the Father.
Note 15 at Php 2:11: Jesus Christ is referred to as "Savior" twice in the book of Acts, while He is referred to as "Lord" over one hundred times. This emphasizes the importance the early church put on complete submission to the authority of Jesus in their lives. In the epistles as well, He is called "Lord" hundreds of times.
Ro 10:9 is probably one of the most important focal points of the confession of Jesus' Lordship. It states, "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved." The New English Bible, Revised Standard Version, Today's English Version, The New International Version, and Williams New Testament all translate Ro 10:9 as confessing "Jesus is Lord."
