Faith in Christ requires an understanding of who he is. Jesus is Savior, and Jesus is Lord (Acts 2:36). Therefore, faith in Christ is infallibly marked not only by trust in his saving work, but also by submission to his Lordship.
The New Testament’s names and titles for Jesus make for a rich and inspiring study. But what is the name that God has given Jesus, the name that is above every name? It often happens that Christians who read this passage assume that the name that is above every name is the name Jesus. But Paul had a different name in mind. He went on to say that God has exalted Christ and given Him the name above every name, “that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father” (Phil. 2:10–11). The name that is above every name is the title that belongs only to God, Adonai (“Lord”), which refers to God as the sovereign one. Because of Jesus’ perfect obedience in the role of a slave, God moved heaven and earth to exalt His Son, and He gave Him the name that is above every name, so that when we hear the name of Jesus, our impulse should be to fall on our knees and confess that He is Lord to the glory of God the Father. When we do so, when we exalt Christ in this way, we also exalt the Father.
