<p>1:6 <i>If we say that we have fellowship with Him and walk in the darkness, we lie and not do the truth</i>- As noted on :5, the allusion to the light and darkness of the prologue in John 1 suggests John is warning against fellowship with the darkness of Judaism, which had rejected the light of Christ. The darkness will later be defined as walking in hatred of our brother (2:11). Jewish attitudes to the Lord Jesus and His Jewish followers were indeed a hatred of their brethren. To walk in the darkness of Judaism was therefore to walk in the darkness of hatred of our brethren. There could be no association with any such darkness, if they had the spirit of Christ.</p><p>John writes of <i>doing</i> the Truth (Jn. 3:20,21; 1 Jn. 1:6)- the truth is a title used for the Lord in John's Gospel, but the knowledge of Him must be 'done'. He and His <i>logos </i>cannot be known purely in the abstract, but must be lived. For He is &quot;the life&quot;. The Lord Jesus was &quot;the Truth&quot; in His life example as well as in His teaching. This tendency to apparently 'know' the Lord Jesus on a purely abstract level is a serious temptation in this&nbsp;internet age.</p>
