The people asked Jesus...
“What must we do to do the works God requires?”
Jesus answered, “The work of God is this: to believe in the one he has sent.”
So they asked him, “What sign then will you give that we may see it and believe you? What will you do? ... (John 6:28-30 NIV)
Jesus had just fed about 5000 men with five small barley loaves and two small fish. He had also just crossed to the other side of the lake without getting into a boat.
How should they have known God had sent Jesus?
Did they comprehend what he was talking about?
Did they do the work?
There is nothing new under the sun.
All glory to God.
