<p>4:23- see on Eph. 1:15.</p><p><i>But you, being renewed in the spirit of your mind</i>- The sensuality of :19 is listed as a work of the flesh (Gal. 5:19). The key to growth was to allow the Spirit they had received to renew them. They were to &quot;be renewed&quot; (AV), they were to allow the process of renovation to operate. And the locality and method of that renewal was by the Spirit within their minds. Again and again it is clear that the arena of the Spirit's operation is within the mind, &quot;the inner man&quot; of chapter 3, and the reference is not to the external manifestations of the Spirit in miraculous gifts. It was this re-newing which could create the new man of :24. The Spirit had been given to them, as to all believers, at their baptism. But some of them were alienated from that life / Spirit of God within them. They were to allow that Spirit free course to make them new again, to form again the new man within them.</p>
