<p>13:21 <em>Perfect you in every good thing to do His will; working in you that which is pleasing in His sight, through Jesus Christ. To whom be the glory for ever and ever. Amen</em>- We work God&rsquo;s will, and He works in us (Gk.). There is a mutuality between God and man. The new covenant involves the blessing of the Spirit, preparing us, perfecting and maturing us, so that we might do God's will in practice. But all this is predicated upon the ongoing work of the Lord Jesus within us. It is the internal gift of the Spirit through which God works within us (Eph. 3:20), and this is an outflow of the new covenant (:20). The &quot;Amen&quot; brings to a close the sermon we have transcripted here (see on :22); and the final appeal to glorify the Lord Jesus would be an appropriate end to breaking of bread sermon.</p>
