The Gospel is God's Law
Jesus(pbuh) was a god-fearing man who followed all the laws that were written in the Torah he even condemned people who did not follow the law.
Jesus did not fulfill the laws of the Old Testament who commanded harm and kill people for various reasons. As an example, you can see the teaching of the Gospel about the woman "surprised in adultery":
"And the scribes and the Pharisees bring a woman taken in adultery; and having set her in the midst, they say unto him, Teacher, this woman hath been taken in adultery, in the very act. Now in the law Moses commanded us to stone such: what then sayest thou of her? And this they said, trying him, that they might have whereof to accuse him. But Jesus stooped down, and with his finger wrote on the ground.
But when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her. And again he stooped down, and with his finger wrote on the ground. And they, when they heard it, went out one by one, beginning from the eldest, even unto the last: and Jesus was left alone, and the woman, where she was, in the midst. And Jesus lifted up himself, and said unto her, Woman, where are they? did no man condemn thee? And she said, No man, Lord. And Jesus said, Neither do I condemn thee: go thy way; from henceforth sin no more. Again therefore Jesus spake unto them, saying, I am the light of the world: he that followeth me shall not walk in the darkness, but shall have the light of life". (Juan 8: 3-12)
ABOUT THE SHABBAT'S LAW OF THE OLD TESTAMENT
Says the Old Testament:
"And while the children of Israel in the wilderness , they found a man gathering sticks on the Sabbath. And those who found him gathering sticks brought him to Moses and Aaron and to all the congregation, and put him in prison, because was not declared what should be done to him. and the Lord said to Moses: man dies, all the congregation shall stone him outside the camp. congregation brought him without the camp, and stoned him, and died, as the LORD commanded Moses" (Numbers 15: 32-36)
That's not what Jesus commanded us:
"At that time Jesus went through the grain fields on the Sabbath, and His disciples were hungry and began to pluck heads of grain and eat. Seeing the Pharisees said unto him, Behold, thy disciples do that which is not lawful to do on the day rest. But he said unto them, Have ye not read what David did when he and those with him were hungry, how he entered the house of God, and did eat the shewbread, which was not lawful to eat neither he nor those who were with him, but only for the priests ? or have you not read in the law that on the Sabbath the priests in the temple profane the sabbath, and are blameless? for I say that one greater than the temple is here. and if you had known what this means, I desire mercy and not sacrifice, not have condemned the innocent, for the Son of Man is Lord of the Sabbath. " (Matthew 12: 1-8)
"Jesus saith unto him, Rise, take up thy bed, and walk.
9 And immediately the man was made whole, and took up his bed, and walked: and on the same day was the sabbath.
10 The Jews therefore said unto him that was cured, It is the sabbath day: it is not lawful for thee to carry thy bed.
11 He answered them, He that made me whole, the same said unto me, Take up thy bed, and walk.........
16 And therefore did the Jews persecute Jesus, and sought to slay him, because he had done these things on the sabbath day.
17 But Jesus answered them, My Father worketh hitherto, and I work.
18 Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God. " (John 5: 8-18)
