John 6: 22-29, What Work Does God Require?

Jesus has just fed five thousand and then crossed the Sea of Galilee, passing the disciples while walking on water. 

John 6: 22-24, Crowds follow
The next day the crowd that had stayed on the opposite shore of the lake realized that only one boat had been there, and that Jesus had not entered it with his disciples, but that they had gone away alone. 
23 Then some boats from Tiberias landed near the place where the people had eaten the bread after the Lord had given thanks. 
24 Once the crowd realized that neither Jesus nor his disciples were there, they got into the boats and went to Capernaum in search of Jesus.

I've repeated these transition verses which we looked at briefly last time.

John 6: 25-29, The work of God
When they found him on the other side of the lake, they asked him, “Rabbi, when did you get here?”

26 Jesus answered, “Very truly I tell you, you are looking for me, not because you saw the signs I performed but because you ate the loaves and had your fill. 
27 Do not work for food that spoils, but for food that endures to eternal life, which the Son of Man will give you. For on him God the Father has placed his seal of approval.”

28 Then they asked him, “What must we do to do the works God requires?”

29 Jesus answered, “The work of God is this: to believe in the one he has sent.”

The crowds discover that Jesus has gone but only one boat is missing and so they are curious about how he crossed the sea.  Jesus doesn't answer this question but challenges the crowds to be interested in more than just physical food.  He, the Son of Man, is interested in providing eternal life. The crowd responds with a question that about what this means, how one does God's work.  The short answer Jesus gives is that trusting in Him is the work of God!
