Right, answer me this: Is it hard for you to love God and your neighbour as Jesus pointed out in MAT 22:37,38? Because if you cannot keep the 10 commandments, that is what you are impying. Jesus said: "If you love me you will keep my commandments. JOHN 14:15".
My own opinion here is that none of us fully and always obeys the Ten Commandments. I know you are sincere. Either I am one of the worst sinners on cc, or I am being honest. If anyone says they can always uphold all of the Ten Commandments I can only say I never have. To always without fail love our neighbour as ourself?(that isn't one of them though is it) Lets not forget Jesus added to the word of the law(he upped the ante so to speak.)
So no I couldn't perfectly uphold the Ten Commandments, but please refer to my final answer on this
Does James 2:10 not say that if you break one you break them all? So if you only keep nine, that means you are keeping some, but not all. If you keep even NINE, you are keeping the law.

Therefore, in not keeping ALL 10, you are a law breaker. And again, IS IT HARD FOR YOU TO LOVE GOD AND YOUR NEIGHBOUR(Mat 22:37,38)?
I believe James 2:10 shows us the futility of trying in any way to be justified, acceptable, or righteous before God by law/the Ten Commandments. Unless you can say that you perfectly without a slip always obey those commandments according to law, yes we have broken them all and are guilty of breaking them all, which would mean in God's eyes we are murderers. Therefore I personally turn to what the Apostle Paul wrote
Did Jesus not say: "I have not come to ABOLISH the law, I have come to FULFILL it. MAT 5:17" In your opinion, does this mean Paul was teaching contrary to what Jesus was teaching? If so, does that not make you worried?
