<p>17:19 <i>And for their sakes I sanctify myself, that they may also be sanctified in truth</i>- The Lord's death was the final act of sanctification in His holy life. If we venture to enquire how exactly He achieved what He did, what His motivations were... we are entering holy ground. But here He states that He did it &quot;for their sakes&quot;, so that we might be sanctified in Him, &quot;the truth&quot; (see on :17,18). His vision, however, was that we would not simply be 'saved' but 'sanctified', which as explained on :17 is a clear allusion to priestly service. He sanctified Himself so that in Him, we would be sanctified- to do priestly service. And the service particularly in view, as noted on :18, was to be sent into the world to save others. We are therefore expected to be proactive in our response to Him. Quite simply, if we behold and believe the things of the cross, we will respond.</p>
