There is another argument why we should not look to the 10 commandments at this time. In Romans 7, Paul writes that the Law of Moses causes sin to be empowered in him! Yes, the Law arouses the inner sinful nature. People will deny this, but it is clearly what Paul is saying if we take his words seriously and do not commit great violence to the text to serve a particular theological agenda. To wit:
5 For while we were in the flesh, the sinful passions, which were aroused by the Law, were at work in [c]the members of our body to bear fruit for death. 6 But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the [d]Spirit and not in oldness of the letter7 What shall we say then? Is the Law sin? May it never be! On the contrary, I would not have come to know sin except [e]through the Law; for I would not have known about [f]coveting if the Law had not said, “You shall not [g]covet.” 8 But sin, taking opportunity through the commandment, produced in me [h]coveting of every kind; for apart from the Law sin is dead. 9 I was once alive apart [j]from the Law; but when the commandment came, sin became alive and I died; 10 and this commandment, which was [k]to result in life, proved [l]to result in death for me; 11 for sin, taking an opportunity through the commandment, deceived me and through it killed me. 12 So then, the Law is holy, and the commandment is holy and righteous and good.
Paul even names one of the 10 :" you shall not covet". And what happens to Paul when he tried to follow that commandment? Things got worse - sin became aroused, was brought to life, it killed him.
And you (who say we should still look to the 10) want to follow in those footsteps?
