In today's Gospel, Jesus tells us a simple but challenging story about a father who asks his two sons to go and work in the vineyard. The first son says, "No, I will not." But later, he changes his mind and goes. The second son says, "Yes, sir," but he does not go. Then Jesus asks a very important question: "Which of the two did his father's will?"

The Gospel reminds us that God is not interested only in what we say; He is interested in what we do with our lives. It is easy to say, "Yes, Lord." We can pray, attend Mass, sing hymns, say our prayers, and speak about our faith. All of these things are important. But Jesus reminds us that faith must eventually become action.
