Romans 3:19-20 NLT

Obviously, the law applies to those to whom it was given, for its purpose is to keep people from having excuses, and to show that the entire world is guilty before God. For no one can ever be made right with God by doing what the law commands. The law simply shows us how sinful we are.

He who passes by and meddles in a quarrel not his own
Is like one who takes a dog by the ears.
