There are no laws for Christians, because "The Just Shall Live By Faith" Romans 1:17.
Here is who the law is for, 1 Timothy 1:9.10. If the shoe fits then wear it.
You misunderstand Paul.
You tried to use Romans 1:17 to speak against obeying Jesus' teachings.
Here is Romans 1:16 For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile. 17 For in the gospel the righteousness of God is revealed—a righteousness that is by faith from first to last, just as it is written: “The righteous will live by faith.”
See how Paul is speaking about having faith and living by faith, but you turn that faith into disobedience.
Paul says have faith in the gospel and what Jesus says, the new law, the law that requires faith.
Faith in what? What does the gospel say? The gospel says that Jesus died for us and his blood washes us clean of the sins we repent of doing. Nowhere anywhere is Paul saying we do not have to obey.
By faith in Jesus' blood versus getting an animal for its blood, as the old law tells us to do.
You also misused 1 Timothy 1:9-10.
Look at the scripture just before the ones you posted.
Look at 1 Timothy 1:8.
1 Timothy 1:8
We know that the law is good if one uses it properly. 9 We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers, 10 for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurers—and for whatever else is contrary to the sound doctrine 11 that conforms to the gospel concerning the glory of the blessed God, which he entrusted to me.
The scriptures say THE LAW IS GOOD if one uses it correctly.
You go against the law all around.
You misuse the law for your false doctrines.
Christians uphold the law, not put it down and condemn others with it, as you do.
Romans 3:31
Do we, then, nullify the law by this faith? Not at all! Rather, we uphold the law.
Now where did you go wrong in your understanding?
You need to study and search that out more, because Paul does NOT contradict himself; AND, true saved do NOT ignore scripture, so forget about ignoring 1 Timothy 1:8 and Romans 3:31.
The law was made for sinners, and we all have sinned. Living by faith means you repent of sins and have those sins washed away and you become born again, a new person without the old sins.
