I am illustrating what I say by talking about slavery because your human nature prevents you from understanding spiritual truth easily. In the past you willingly did the immoral and unlawful things that your minds compelled your bodies to do [MET], just like slaves do what their masters compel them to do. As a result, you did even more unlawful things. Now, you need to willingly allow your minds to compel your bodies to act righteously [MET], in order that you will behave in a holy/pure way.
