<p>6:29 <i>Jesus answered and said to them: This is the work of God- that you believe in him whom He has sent</i>- God's work is understood in the context here as miracles. The people wanted to know how they might perform God's works, miracles like making free bread. And as was ever His style, the Lord turns the words of the question another way. God's work is that we believe. Human belief is therefore His work- which we must allow to happen to us, rather than seeking to do works. It's rather like David asking to build God a house, and being told that instead, God would build him a house- if he and his children allowed the way of the Spirit to operate. But this response was totally missed by the crowd- they wanted another miracle (:30), clearly in the hope that again they might materially benefit from it.</p>
