<p>8:45 <i>But because I tell the truth, you do not believe me</i>- Truth is what makes a person believe the speaker. But the Jews did not believe exactly because the Lord told them &quot;the truth&quot;. The &quot;truth&quot; in view is not therefore intellectually pure exposition. They did not believe because they were dominated by sin, &quot;the devil&quot;, and sin is essentially a lie. So their sense of truth and error was inverted. &quot;The truth&quot; as explained on :32 was the Lord's sinless life, His Spirit; hence He challenges them in :46 as to who could convict Him of sin. &quot;The truth&quot; He told was that He was sinless. They did not want to believe that; it demanded too much, that a man of their nature could be sinless, and that His Spirit could enter them and transform their lives so as not to be servants of sin.</p>
