"Jesus is LORD":
A few uses of confessions in the New Testament

Jesus is the focus of salvation-history, Christology, and theology:

1 Cor. 15:3-5 (cf. Isa. 53, Hos. 6:2, Jon. 2:1?): "For I delivered to you as of first importance what I also received, that Christ died for our sins in accordance with the scriptures, that he was buried, that he was raised on the third day in accordance with the scriptures, and that he appeared to Cephas, then to the twelve...."

1 Tim. 3:16: "Great indeed, we confess, is the mystery of religion: He was manifested in the flesh, vindicated in the Spirit, seen by angels, preached among the nations, believed on in the world, taken up in glory."

Mark 8:29: "On the way he asked his disciples, 'Who do people say that I am?' And they hold him, 'John the Baptist; and others say, Elijah; and others one of the prophets.' And he asked them, 'But who do you say that I am?' Peter answered him, 'You are the Christ.'"

1 Cor. 12:3: "Therefore I want you to understand that no one speaking by the Spirit of God ever says "Jesus be cursed!" and no one can say "Jesus is Lord" except by the Holy Spirit."

Acts 2:36 (cf. Ps. 110:1): "Let all the house of Israel know assuredly that God has made him both Lord and Christ, this Jesus whom you crucified."

Phil. 2:11 (cf. Isa. 45:22-23): "at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess 'Jesus, Christ, Lord,' to the glory of God the Father."

1 Cor. 8:6 (cf. Ps. 136:2-3): "for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist."

2 Cor. 13:14: "The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all."

1 John 3:23-24: "And this is his commandment, that we should believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. All who keep his commandments abide in him, and he in them. And by this we know that he abides in us, by the Spirit which he has given us."

1 John 4:13-15: "By this we know that we abide in him and he in us, because he has given us of his own Spirit. And we have seen and testify that the Father has sent his Son as the Savior of the world. Whoever confesses that Jesus is the Son of God, God abides in him or her, and he or she in God."

Matt. 28:19: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit...."

Rom. 1:3-4: "... the good news concerning his Son, who was descended from David according to the flesh and designated Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord...."

Rom. 10:8-9 (cf. Deut. 30:14): "What does it say, 'The word is near you, on your lips and in your heart' (that is, the word of faith which we preach); because, if you confessed with your lips that Jesus is Lord and believed in your heart that God raised him from the dead, you would be saved."
