<p>9:4 <i>We must work- </i>We are lights in the dark world (Mt. 5:14; Phil. 2:15), because we are in Christ, the light of the world (Jn. 9:5). Notice how in the preceding verse, Jesus said spoke of how &ldquo;I must work the works of him that sent me&rdquo; (Jn. 9:4 AV), yet the RV reflects the manuscript difficulties by giving &ldquo;We must work&rdquo;. Could it be that the Lord said: &lsquo;I must work, we you in me must work&rsquo;? The Lord Jesus was the light of the world on account of His resurrection: &ldquo;He first by the resurrection from the dead should proclaim light both to the Jewish people and to the Gentiles&rdquo; (Acts 26:23 RV). If we are baptized into His death and resurrection, we too are the light of this world in that the light of His life breaks forth in us. And this is exactly why belief in His resurrection is an imperative to preach it. And it&rsquo;s why the great commission flows straight out of the resurrection narrative.</p><p><i>The works of Him that sent me, while it is day. The night comes, when no one can work</i>- In the prologue, the night is the darkness of Jewish unbelief, and the light is that of the person of the Lord Jesus and His life. The coming of the night therefore refers to the Lord's death, the temporary extinguishing of the light by the darkness. There would be no works / miracles doable then, so the Lord was keen to bring light to people whilst He could. And likewise people only had a very short frame of opportunity to be in the light. Perhaps the Lord was speaking in a kind of soliloquy when He mused that &quot;the night comes, when no man can work&quot;, and therefore man should walk and work while he has the light (Jn. 9:4, quoting Ecc. 9:10). He was speaking, in the context, not only of His own zeal to 'work' while He had life, but also applying this to His followers.</p>
