What does the confession 'Thou art the Christ, the Son of the living God' mean?
The confession means recognizing Jesus as the Christ, the Messiah, the Son of the living God, who comes to fulfill the covenant's third part as King Redeemer, prophet and priest. In John 11, Martha confesses Him as the Christ who should come into the world.
Les teaches that the gospel of the kingdom precipitated this kind of confession: “Thou art the Christ, the Son of the living God.” He explains that this meant Jesus is the Messiah coming to fulfill the third part of that covenant—the King Redeemer, the prophet and priest. In John 11, after Jesus tells Martha, “I am the resurrection and the life,” Martha answers, “Yea, Lord, I believe thou art the Christ, the Son of the living God, who should come into the world.” The context emphasizes that her confession did not add “and die for me, and be raised from the dead”; her confession of faith was that He is the Christ, the Son of the living God, who should come into the world.
