You claim Jesus was a teacher of the law, so what is your problem.

Matthew 8:1 When he was come down from the mountain, great multitudes followed him. 8:2 And, behold, there came a leper and worshipped him, saying, Lord, if thou wilt, thou canst make me clean. 8:3 And Jesus put forth his hand, and touched him, saying, I will; be thou clean. And immediately his leprosy was cleansed. 8:4 And Jesus saith unto him, See thou tell no man; but go thy way, shew thyself to the priest, and offer the gift that Moses commanded, for a testimony unto them.
Leviticus 14:2 This shall be the law of the leper in the day of his cleansing: He shall be brought unto the priest: 14:3 And the priest shall go forth out of the camp; and the priest shall look, and, behold, if the plague of leprosy be healed in the leper; 14:4 Then shall the priest command to take for him that is to be cleansed two birds alive and clean, and cedar wood, and scarlet, and hyssop: 14:5 And the priest shall command that one of the birds be killed in an earthen vessel over running water: 14:6 As for the living bird, he shall take it, and the cedar wood, and the scarlet, and the hyssop, and shall dip them and the living bird in the blood of the bird that was killed over the running water: 14:7 And he shall sprinkle upon him that is to be cleansed from the leprosy seven times, and shall pronounce him clean, and shall let the living bird loose into the open field.
Leviticus 14 goes on to relate more of that...
Moving on, we find...
Matthew 23:1 Then spake Jesus to the multitude, and to his disciples, 23:2 Saying, The scribes and the Pharisees sit in Moses' seat: 23:3 All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not.
Matthew 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 28:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Romans 2:17 Behold, thou art called a Jew, and restest in the law, and makest thy boast of God,
2:18 And knowest his will, and approvest the things that are more excellent, being instructed out of the law; 2:19 And art confident that thou thyself art a guide of the blind, a light of them which are in darkness, 2:20 An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law. 2:21 Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal? 2:22 Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege? 2:23 Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
2:24 For the name of God is blasphemed among the Gentiles through you, as it is written.
2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
Romans 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God. 3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: 3:23 For all have sinned, and come short of the glory of God; 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus: 3:25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
3:26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
In my understnading of Mid-Acts Dispensationalism, my above is...
A DISTINCTION...
BETWEEN the Lord's AND the Twelve's ministry TO ISRAEL UNDER THE LAW, on the one hand...
AND...
The Apostle Paul's DISTINCTIVE...
DUE TIME...
Ministry to ALL...
WITHOUT distinction...
THIS SIDE OF...
The righteousness of God...
WITHOUT The Law.
