Clearly the scripture teaches obedience to the commandments of God under Christ is important and disciples of Christ should strive against sin to obey God (Hebrews 12:4). For we shall all be judged (2 Cor 5:10; Rom 6:1-2; John 8:31-32).
But notice Paul said he failed in keeping the law (e.g., Romans 7:11-25; Gal 5:17).
Paul and the other apostles clearly assert salvation is not dependent on perfectly keeping the law (e.g. Acts 15:5, 9-11, 19-29). Indeed scripture says if we break one part of the law we are guilty of all (James 2:10).
Indeed scripture indicates the foundation for salvation is Jesus Christ and him crucified shedding his blood for remission of sins (e.g , John 14:1-6; 1 Cor 2:2; Ephesians 1:7) rather than the foundation being keeping the law.
That is to say the foundation for salvation is one’s acceptance of Christ and his teachings and striving to be obedient under the Holy Spirit. That is the good news of the Gospel of Jesus Christ.
But in the end it is what Christ decides no matter what we think for only Christ has the power to send to heaven or hell. I nor any other human possess such power and I am glad we don’t.
Saying salvation is not dependent on perfectly keeping the law under Christ is not rebelling against God.
Saying that some laws are no longer in effect (e.g. simple laws like male circumcision) are no longer commanded as its purpose is no longer ceremonially useful) is also not rebelling against God.
Can anyone name one person the bible presents other than Christ who perfectly kept the law of God?
