Jesus told this story:
Matthew 21:28-32 (NIV)
“There was a man who had two sons. He went to the first and said, ‘Son, go and work today in the vineyard.’
“‘I will not,’ he answered, but later he changed his mind and went.
“Then the father went to the other son and said the same thing. He answered, ‘I will, sir,’ but he did not go.
“Which of the two did what his father wanted?”
Your will be done. Do you mean what you pray?
Good question.
The words roll off our tongues so easily, but our feet may follow reluctantly–or run the other way.
