So you don't see how you are contradicting yourself? You're claiming you're a convert to the religion of Judism, which requires you keep the law. Yet, the early church understood the law was a yoke that the fathers were not able to bear.
So, those same Jewish believers you speak of did not continue to follow the law realizing it was contrary to the righteousness of God...which is through faith.
Acts 15:5
But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.
6 And the apostles and elders came together for to consider of this matter.
7 And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;
9 And put no difference between us and them, purifying their hearts by faith.
Acts 15:10 Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
11 But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
Galatians 5:1
Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
Shalom.
It is not wrong to keep God's law. It may have been a burden, or appeared as a burden, both with different understandings of what this might mean, but it has not been abolished. If you are a convert from among the Gentiles, start with the essentials. Remember, the Noahide laws are for all nations.
Shalom.
Jacob
