<p>11:10 <i>But if a man walks in the night, he stumbles, because the light is not in him</i>- In John's letters, there are many allusions back to John's Gospel. This is an example. The reason for the connections is because the gospel of John is as it were a transcript of John's preaching of the Gospel; it became written down as a text for the basic instruction of John's converts. Once communities of believers had been baptized and established on this basis, John then wrote letters to them. And it is understandable that he would base his appeals for Christian living on the facts of the Gospel message which the converts had first learnt in the Gospel of John. The allusion to Jn. 11:10 is in 1 Jn. 2:10,11: &quot;He that loves his brother abides in the light, and there is no occasion of stumbling in him. But he that hates his brother is in the darkness and walks in the darkness, and does not know where he goes, because the darkness has blinded his eyes&quot;. The context of Jn. 11:10 is about a beloved brother, Lazarus, brother of sisters Martha and Mary. John is surely making the point that if the Lord and the disciples had not gone to raise Lazarus, because they feared for their own wellbeing, then this would effectively have been hating their brother. Here we see powerfully presented the full extent of sins of omission; to not respond to the need of Lazarus, citing fear of the Jews, would be to effectively hate that brother. And we all likely need such exhortation as to the real import of omitting to do what we could. The Lord walked those 12 hours to Bethany with the disciples following, willing if necessary to &quot;die with Him&quot;. And the context in 1 Jn. 2 also alludes to this: &quot;He that says he abides in him, ought also walk even as he walked&quot; (1 Jn. 2:6).</p>
