You don't obey the law. You don't even come close. The law says, "Love your neighbor as yourself" Do you love your neighbor as yourself? Jesus told the rich young ruler to go sell all that he had and give it to the poor. Have you done that? No, you are not about to do that are you? What the law will make you is a hypocrite just like the Pharisees.
Your argument literally just said it is impossible to love your neighbor as yourself. By your definition, if I have not sold all that I have, and given it to the poor, then that means I don't love my neighbor as myself. That means the same for you. That means you lack in the necessary love that is needed for a Christian, and therefore are unfit for heaven.
Christ was only speaking to that young,
rich man (which I am not) to sell all that he had.
As for the law, I obey it, because I believe Christ made me free from sin. He gives me the power to obey Him. He lives in me. Now sure, we fall and make mistakes, and that is what confession and repentance is for. And when you repent you are wiped clean, as if you had never sinned before.
He who claims that one cannot keep God's law with the help that Christ gives Him does not know Christ.
Philippians 4:13 I can do all things through Christ which strengtheneth me.
Romans 7:25 I thank God through Jesus Christ our Lord.
So then with the mind I myself serve the law of God; but with the flesh the law of sin.
