Paul Does Not Have the Law Written in His Heart

Paul writes of himself to the Romans, What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet. But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead. For I was alive without the law once: but when the commandment came, sin revived, and I died. And the commandment, which was ordained to life, I found to be unto death. For sin, taking occasion by the commandment, deceived me, and by it slew me. Wherefore the law is holy, and the commandment holy, and just, and good. Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.^{Romans 7:7-13}

Paul is saying that he only knew of sin because of the law. Paul also wrote earlier in his letter to the Romans, For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another.^{Romans 2:14, 15}

So, is Paul was worse than these certain gentiles, who had the law written in their heart? Paul then writes that the law told him what was sin and what was not. As a Pharisee, Paul would have needed such outside instruction.

James writes, Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: But every man is tempted, when he is drawn away of his own lust, and enticed.^{James 1:13, 14} This is more in line with what we would expect an apostle to say, "I was tempted to sin by my own desire." Paul says, "I learned I sinned because of the law."

Value of this Evidence

This is decent evidence against Paul's case of being a true apostle because he says that he could not follow the law without it written down, even though gentiles can follow it. And since Jesus did not demolish the law, but strengthened and fulfilled it, Paul would not be able to fulfill Jesus's law either.
