“Do you begrudge my generosity?” (20:15). God chooses to be generous and gracious to all who respond to his call. Jesus redefined greatness in terms of service, not authority (20:26). The religious leaders were not pleased, as they based their spirituality on external religion rather than authentic faith. They did not recognize the true Messiah in spite of the signs (21:14-15). The parable of the sons reveals that a superficial “yes” to God is not good enough.
God has already demonstrated His gracious love. Our part is to be sensitive to the voice of Jesus in our lives, so that we are quick to respond in obedience to Him.
