<p>2:23 <em>Now when he was in Jerusalem at the Passover, during the feast, many believed in his name when they saw the signs which he did</em>- Israel also saw signs and believed for a moment, but not for long. As noted on :24 and :25, such belief is merely surface level. But it is still noted for what it was; it was not insignificant. The Lord Himself learnt from this, so that when faced with the appeal to come down from the cross so that they would believe, He resisted. Faith comes by hearing God's word; not by seeing miracles. The miracles recorded by John were all object lessons, intended to visually enhance the message being taught, and were not performed simply to meet human need.</p>
