<p>3:7 <em>Things in which you also once walked, when you lived in these things</em>- The parallel Eph. 2:2 says that &quot;in which you once walked according to the course of this world, according to the prince of the powers of the air, according to the spirit that now works in the sons of disobedience&quot;. That 'spirit' is here defined as that of sexual abandon and lack of internal mental control. This arises from within the flesh; and not as a result of some cosmic being controlling us.</p>
