<p>6:36 <i>But I say to you: That you have seen me, and still you do not believe</i>- &quot;Seeing&quot; may be being used here as it is often in John- to refer to understanding. The Jews saw the Son coming to them and said &quot;Come let us kill Him&quot;. They knew Him, and His relationship to the Father (7:28). But still they refused to believe. They wanted to be given the bread of life, Messiah, and He was standing before them. They had seen Him, and seen His creation of manna / bread, but still did not believe. Miracles do not produce lasting faith- that is one of the subtexts of John, especially relevant as he was preaching and ministering to converts in days when the miraculous gifts were disappearing.</p>
