Jesus’ parable of the Two Sons is a perfect rebuttal to the chief priests and elders refusal to answer Jesus’ question about John the Baptist. They know that he can challenge them on their lack of faith, yet he reminds them that they can turn any time to the Father’s will and believe in the one whom he has sent to bring salvation. That still applies today: Regardless of our having said no to the Father’s will, we can turn back and believe in Christ. And likewise, if we have said we will do the Father’s will and not done it, we can turn around and begin doing it.
