A.T. Robertson Commentary Philippians 2:11

"and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father." — Philippians 2:11 (ASV)

Should confess (εξομολογησητα). First aorist middle subjunctive of εξομολογεομα with ινα for purpose.

Lord (Κυριος). Peter (Acts 2:36) claimed that God made Christ "Lord." See also 1 Corinthians 8:6; 12:3; Romans 10:9. Kennedy laments that the term Lord has become one of the most lifeless in the Christian vocabulary, whereas it really declares the true character and dignity of Jesus Christ and "is the basis and the object of worship."
