The apostle here gives a remarkable proof of the divinity of our Saviour. He could not possibly be more express. He had said in the preceding verse, that all men should appear before the tribunal of Christ; to prove this assertion, he adduces this testimony of the prophet Isaias: “As I live, saith the Lord, every knee shall bend before me, and every tongue shall confess to God.” (Isaias chap. xlv.) Thus shall all acknowledge the power, the divinity, and sovereign dominion of Christ, by bending the knee; and by confessing to him, shall acknowledge him for the master and judge of all mankind.
