Rom 3:31 is a great verse. Paul spent the preceeding ten verses telling his readers they had no righteousness of obeying the law and were justified apart from works. What would some of his readers have thought reading that? ''If we are saved apart from obeying the law we can live as we like for our righteousness is apart from obeying the law. Hence rom3:31. But did Paul mean in that verse we would perfectly obey the letter of the ten commandments he said was the letter that kills, the ministry of death and condemnation? You must read the bible as one cohesive whole, and discern beyond the letter itself, otherwise you have no true understanding of the message of scripture.
Rom7:7&8 is great truth also. Paul wrote that as part of his explanation of why he had to die to righteousness of obeying the law. But if you preach, that obedience to the law is required to remain in a saved state, either to prove you love Jesus, and are willing to bey him, or because sin bars you from heaven, you are in reality preaching righteousness of obeying the law. For anyone who believes you must then base their Christianity on whether they obey the law or not. Justification hinges on observing the law

multiple verses to make sure you interpret the single verse correctly the Bible doesn't contradict itself.
perfectly obey isn't what teach, i say aim to obey the law because thats what you do when you love someone.
We can't keep the law ourselves.
We can't obey it with this fallen nature.
Jesus is our Righteousness because He perfectly kept the law.
By faith Jesus will help us to obey it.
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
Can you see how the flesh fails and that the Spirit succeeds, can you see how we fail in the flesh but when we walk in the Spirit we succeed.
Justification does not hinge on obedience, Turn it around, obedience come as a result of justification. Faith is the key to this.
Heb 11:5 By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
