Jesus is Jehovah/YHVH God's holy servant;
Isa 42:1-8 Behold, My servant, whom I uphold; My chosen, in whom My soul delighteth: I have put My spirit upon him; he will bring forth justice to the Gentiles.
2 He will not cry, nor lift up his voice, nor cause it to be heard in the street.
3 A bruised reed will he not break, and a dimly burning wick will he not quench: he will bring forth justice in truth.
4 He will not fail nor be discouraged, till he have set justice in the earth; and the isles shall wait for his law.
5 Thus saith God Jehovah, He that created the heavens, and stretched them forth; He that spread abroad the earth and that which cometh out of it; He that giveth breath unto the people upon it, and spirit to them that walk therein:
6 I, Jehovah, have called thee in righteousness, and will hold thy hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles;
7 to open the blind eyes, to bring out the prisoners from the dungeon, and them that sit in darkness out of the prison-house.
8 I am Jehovah, that is My name; and My glory will I not give to another, neither My praise unto graven images.
Acts 4:24-30 And they, when they heard it, lifted up their voice to God with one accord, and said, O Lord, thou that didst make the heaven and the earth and the sea, and all that in them is:
25 who by the holy spirit, (by) the mouth of our father David thy servant, didst say, Why did the Gentiles rage, And the peoples imagine vain things?
26 The kings of the earth set themselves in array, And the rulers were gathered together, Against the Lord, and against His Anointed:
27 for of a truth in this city against Thy holy servant Jesus, whom Thou didst anoint, both Herod and Pontius Pilate, with the Gentiles and the peoples of Israel, were gathered together,
28 to do whatsoever Thy hand and Thy council foreordained to come to pass.
29 And now, Lord, look upon their threatenings: and grant unto thy servants to speak thy word with all boldness,
30 while Thy stretchest forth Thy hand to heal; and that signs and wonders may be done through the name of Thy holy servant Jesus.
As Jehovah's holy servant, Jesus preached exactly what his God commanded him to preach;
John 12:49-50 For I spake not from myself; but the Father that sent me, He hath given me a commandment, what I should say, and what I should speak. 50 And I know that His commandment is life eternal: the things therefore which I speak, even as the Father hath said unto me, so I speak.
Jesus taught his God's plan, his God's logos/word, and covered the entire scope of his God's gospel. The gospel of the kingdom, the necessity of works, the necessity of faith, the necessity of love and obedience. Jesus more specifically defined sin, and judgment.... and righteousness and reward.
Jesus taught about the future role of the apostles, and his own future responsibilities.
